Towards the end of the the function there is a call to `FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units. That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY` is left alone, and is not scaled. Patch from Eric Muller <emuller@amazon.com>. commit bed960d9484df1a0c9547ba6855f457d6629ffb5 Author: Werner Lemberg <wl@gnu.org> Date: Thu Sep 24 09:31:56 2020 +0200 * src/base/ftobjs.c (FT_Load_Glyph): Trace glyph metrics. commit 3ce0df52e2bba8a8f788a05c705b90fd10275665 Author: Werner Lemberg <wl@gnu.org> Date: Tue Sep 22 20:05:37 2020 +0200 [meson] Move auxiliary scripts to `builds/meson`. Suggested by Alexei. * scripts/*.py: Move meson scripts to... * builds/meson/*.py: ... this new location. * meson.build: Updated. commit d686f2ff9c40235085558fed91a57d05c7656335 Author: David Turner <david.turner.dev@gmail.com> Date: Tue Aug 25 20:52:32 2020 +0200 Add python script for building tarballs. * scripts/make_distribution_archives.py: New file. This standalone Python script should be equivalent to running `make dist` with the Make-based build system, with the following minor differences: - Since `make distclean` doesn't always clean up `objs/` properly, `make dist` archives may contain some stale binaries like `objs/.libs/libfreetype.so.6` or others. - `config.guess` and `config.sub` are not updated unless option `--gnu-config-dir=DIR` is used to specify the location of these files. - Some bits of the auto-generated reference documentation may appear in slightly different order, probably due to issues related to mkdocs and docwriter. As an example, the call scripts/make_distribution_archives.py /tmp/freetype2-dist creates the following files under `/tmp/freetype2-dist`: freetype-<version>.tar.gz freetype-<version>.tar.xz ft<winversion>.zip commit 46417607e67f89a5c9948d4deed6ad8ead51318d Author: Werner Lemberg <wl@gnu.org> Date: Mon Sep 21 09:03:13 2020 +0200 * scripts/extract_freetype_version.py: Fix regex typos. commit 66978a58874169c6a4f2f984a7461e2901901784 Author: David Turner <david.turner.dev@gmail.com> Date: Sun May 17 18:45:41 2020 +0200 Add Meson build project file. Example usage: # Configure Meson build in directory `build-meson` to generate # release binaries comparable to to the ones from the # autotools/make build system. meson setup build-meson \ --prefix=/usr/local \ --buildtype=debugoptimized \ --strip \ -Db_ndebug=true # After configuring the Meson build with the above command, # compile and install to `/usr/local/`; this includes a pkg-config # file. ninja -C build-meson install # Alternatively, compile and install to `/tmp/aa/usr/local/...` # for packaging. DESTDIR=/tmp/aa ninja -C build-meson install # Generate documentation under `build-meson/docs`. ninja -C build-meson docs Library size comparison for stripped `libfreetype.so` generated by all three build systems: - Default build (autotools + libtool): 712 KiB - CMake build (RelWithDebInfo): 712 KiB - Meson build: 712 KiB * meson.build: New top-level Meson build file for the library. * meson_options.txt: New file. It holds user-selectable options for the build, which can be printed with `meson configure`, and selected at `meson setup` or `meson --reconfigure` time with `-D<option>=<value>`. * scripts/parse_modules_cfg.py: A script invoked by `meson.build` to parse `modules.cfg` and extract important information out of it (i.e., the list of modules). * scripts/process_ftoption_h.py: New script invoked by `meson.build` to process the original `ftoption.h` file. It enables or disables configuration macro variables based on the available dependencies. This is similar to what other build systems are using (i.e., Meson's `configure_file()` command is not used here). * scripts/extract_freetype_version.py: New script invoked by `meson.build` to extract the FreeType version number from `<freetype/freetype.h>`. * scripts/extract_libtool_version.py: New script invoked by `meson.build` to extract the libtool `revision_info` data from `builds/unix/configure.raw`, and to generate the corresponding shared library suffix. * scripts/generate_reference_docs.py: New script invoked by `meson.build` to generate the FreeType 2 reference documentation (using the `docwriter` and `mkdocs` packages, which must be already installed). commit ab6a21b73314ef302299b47b1707f5b2d03826cf Author: Alexei Podtelezhnikov <apodtele@gmail.com> Date: Fri Sep 18 22:32:20 2020 -0400 Documentation updates. commit 20186d1be6415d1bd7cb79ac56f1b806c26b677c Author: Alexei Podtelezhnikov <apodtele@gmail.com> Date: Fri Sep 11 23:47:54 2020 -0400 [raster] Improve the second pass (#58373). Besides dropout control the second horizontal sweep is supposed to clean up straight horizontal edges that are mishandled by the first vertical sweep when a line passes through pixel centers. This line would present as perfectly aligned span edges in the second sweep. * src/raster/ftraster.c (Horizontal_Sweep_Span): Replace the old implementation with a better one focusing on aligned span edges only. commit c3721642f1d373f363d02081a94f24984960484e Author: Alexei Podtelezhnikov <apodtele@gmail.com> Date: Fri Sep 11 23:13:02 2020 -0400 [raster] Tune SMART macro (#58352). Windows seems to perform smart dropout control at 26.6 precision. To mimick Windows independent of increased precision, we need to tweak the macro so that some close calls break down rather than up. * src/raster/ftraster.c (SMART): Tweak the macro. commit cb4733136992265ba8b52c5f009864a0b7769949 Author: Alexei Podtelezhnikov <apodtele@gmail.com> Date: Tue Sep 8 22:41:53 2020 -0400 [raster] Introduce SMART macro. * src/raster/ftraster.c (SMART): New macro for smart dropout rounding. (Verstical_Sweep_Drop, Horizontal_Sweep_Drop): Use it. commit 3594eaee595f174fc6d9f39f55e9918aa4eaa9e7 Author: Alexei Podtelezhnikov <apodtele@gmail.com> Date: Tue Sep 8 22:20:11 2020 -0400 [raster] Improve tracing. commit fa82803f46aa27e5f173d35a3e2bffcd67dc2e5a Author: Nikolaus Waxweiler <madigens@gmail.com> Date: Thu Sep 3 11:11:41 2020 +0100 * ChangeLog: Add entry for last commit. commit 69353a19a197b0ab89b8382966c07f072fed8453 Author: Boris Dalstein <dalboris@gmail.com> Date: Tue Aug 25 13:53:54 2020 +0200 Export version info (#58935) commit 600d59e343a0d6529a2cd714bf90b70a107b39d7 Author: Alexei Podtelezhnikov <apodtele@gmail.com> Date: Wed Sep 2 15:48:03 2020 -0400 [truetype] Reduce Infinality footprint (cont'd). * src/truetype/ttinterp.c (Ins_DELTAP): Shrink variable scope.

(no left margin instead). - 2 empty lines between variable declarations and statements in C blocks. (only 1 is kept). { int x = ...; foo(x); } becomes { int x = ...; foo(x); } - Aignment of declarations uses 2 spaces to separate types and variable names (only 1 space is kept). int x; => int x; int y; int y; - The start used for output parameters in function signature should be near the variable name (always near the type). void foo(int* input_ptr, int *output_ptr) => void foo(int* input_ptr, int* output_ptr) commit b7c467b6efa5a91945854de81632be45d6f360ff Author: Werner Lemberg <wl@gnu.org> Date: Wed Jul 15 09:15:25 2020 +0200 [doc] Stem darkening is off by default for CFF driver.

Set correct value of `face->num_faces' for WOFF2 fonts. This is being handled separately because we only load the tables for the requested font face in `woff2_open_font' and create a single-face sfnt stream. The full discussion is at: https://lists.gnu.org/archive/html/freetype-devel/2019-08/msg00000.html * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `woff2_num_faces'.

We do this by using `totalSfntSize' as an initial reference, and extending the buffer when required. This reduces rendering time considerably. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add `totalSfntSize', rename `total_sfnt_size' to `actual_sfnt_size'. * src/sfnt/sfwoff2.c (write_buf): Add parameter `dst_size' to keep track of and update total size of stream. (WRITE_SFNT_BUF, WRITE_SFNT_BUF_AT): Modify macros accordingly. (pad4, store_loca, reconstruct_glyf, reconstruct_hmtx, reconstruct_font): Update parameters to accept `sfnt_size'. (woff2_open_font): Add variable `sfnt_size'. Use WOFF2 header field `totalSfntSize' as initial reference (if value makes sense) and allocate `totalSfntSize' bytes for the sfnt stream. `write_buf' handles reallocation if and when required. Also resize the stream to `actual_sfnt_size' after reconstruction. commit 4d9b3d1d506c2da2cc078369ed130fb2b6994bb2 Author: Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> Date: Tue Jul 16 02:45:03 2019 +0530 [woff2] Reconstruct `loca', `hmtx', and swap out stream. Add necessary functions to reconstruct loca and hmtx tables (the two remaining tables that can have a transform). `woff2_open_font' is now capable of loading a woff2 font face. This code may still need more refining and better memory management. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add total (final) size of sfnt stream. (WOFF2_InfoRec): Add header checksum value. * src/sfnt/sfobjs.c (sfnt_open_font): Change `face_instance_index' parameter to its pointer so its value can be modified by `woff2_open_font'. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF_AT): New macro to write into sfnt buffer at given position. (write_buf): Add parameter `extend_buf' which allows caller to specify whether buffer should be reallocated before copying data. (WRITE_SFNT_BUF): Updated. (pad4, store_loca, reconstruct_htmx): New functions. (reconstruct_glyf): Calculate loca values and store them. (reconstruct_font): Call `reconstruct_hmtx', write table record entries, and calculate table checksums. Also calculate font checksum and update `checksumAdjustment' entry in head table. (woff2_open_font): Open stream for sfnt buffer, swap out input stream and return. * src/sfnt/sfwoff2.h (woff2_open_font): Modify parameter to accept pointer to `face_index'. commit e3953e5410eaeec7ae49dbda26be6e4b1ca5d26c Author: Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> Date: Sat Jul 13 03:14:17 2019 +0530 [woff2] Reconstruct transformed `glyf' table. Reconstruct `glyf' table if it is transformed in the uncompressed table stream. Also add necessary structures, macros and functions. * include/freetype/internal/wofftypes.h (WOFF2_InfoRec, WOFF2_SubstreamRec, WOFF2_PointRec): New structures. (WOFF2_TableRec): s/OrigLength/dst_length/. * src/sfnt/sfwoff2.c (READ_255USHORT, READ_BASE128): Use `FT_SET_ERROR' to set implicit `error' variable. (WRITE_SHORT): New macro. (N_CONTOUR_STREAM, N_POINTS_STREAM, FLAG_STREAM, GLYPH_STREAM, COMPOSITE_STREAM, BBOX_STREAM, INSTRUCTION_STREAM): New macros to refer to substreams of the transformed `glyf' tables. (Read255UShort, ReadBase128): Return errors set by `FT_READ_XXX' macros. (with_sign, safe_int_addition): New functions to add sign to values based on a flag and perform safe addition respectively. (triplet_decode): Decode variable-length (flag, xCoordinate, yCoordinate) triplet for a simple glyph. See https://www.w3.org/TR/WOFF2/#triplet_decoding (store_points, compute_bbox, composteGlyph_size, reconstruct_glyf): New functions. (reconstruct_font): Call `reconstruct_glyf'. * src/sfnt/sfwoff2.h: Add required constants. * src/sfnt/woff2tags.h: Move out constants to `sfwoff2.h'. commit 81cf5326d59282265ccc0911050005a4b5d20a99 Author: Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> Date: Sat Jul 6 18:05:18 2019 +0530 [woff2] Copy un-transformed tables to sfnt stream. Copy un-transformed tables to the sfnt stream. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF): New macro. (write_buf): New function. Extend memory of `dst' buffer and copy bytes from `src'. (compute_ULong_sum): New function. Calculate checksum of table. (reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte** sfnt_bytes'. This has been done because we reallocate memory to `sfnt' multiple times, which may change the pointer value of `sfnt'. This new pointer must be propogated back to the caller. Same reason for using a double pointer in `write_buf'. * src/sfnt/woff2tags.h (WOFF2_DEFAULT_MAX_SIZE): New macro used for overflow checking. commit 106bacf5022e8c7c8bdcd8407efd64fb6db182b4 Author: Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> Date: Fri Jul 5 01:09:52 2019 +0530 [woff2] Create stream for uncompressed buffer. Uncompressed buffer is now an `FT_Stream'. Perform basic checks and start iterating over tables. * src/sfnt/sfwoff2.c (stream_close, find_table, read_num_hmetrics): New functions. (reconstruct_font): Modify parameters and iterate over tables.

WOFF2 compressed stream is now uncompressed if Brotli is available. This data is stored in a separate buffer (uncompressed_buf) because it does not contain direct table data. Certain tables have transformations applied to them, and they must be reconstructed before we can write those tables to the SFNT stream. `face_index' is now being passed as a parameter to `woff2_open_font'. * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `face_instance_index'. * src/sfnt/sfwoff2.c (woff2_uncompress): New function. (woff2_open_font): Call `woff2_uncompress'. (compute_first_table_offset): Fix return type. * src/sfnt/sfwoff2.h (woff2_open_font): Modify declaration. commit 732da8a4b7d3e28da5d89eeeafb7dbbe965f0870 Author: Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> Date: Sun Jun 30 04:15:55 2019 +0530 * builds/unix/configure.raw: Change argument name to `brotli'. commit 9443a1bc3e6cfa315db976ff80f6c5e91b12b387 Author: Nikhil Ramakrishnan <ramakrishnan.nikhil@gmail.com> Date: Fri Jun 28 01:01:17 2019 +0530 Add Brotli dependency and required checks.

As originally intended, a Type 1 SEAC charstring would be used for an accented glyph (like `acaron' or `uumlaut'), where the advance width of the SEAC glyph is the same as that of the `base' glyph (like `a' or `u'). In this case it is not uncommon for the SEAC glyph to not use an (H)SBW opcode of its own but to rely on the value from the base glyph. However, out-of-spec fonts also use SEAC glyphs for ligatures (like `oe' or `fi'), and in those cases the overall advance width is greater than that of the `base' glyph. For this reason we have to allow that the SEAC glyph can have an (H)SBW value of its own, and if it has, retain this value, rather than the one from the base glyph. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>: Implement it. commit 8cf046c38d4c6ada76ba070562beff0d5041f795 Author: Werner Lemberg <wl@gnu.org> Date: Mon Jul 1 13:54:54 2019 +0200 * Version 2.10.1 released. ========================== Tag sources with `VER-2-10-1'. * docs/VERSION.TXT: Add entry for version 2.10.1. * README, Jamfile (RefDoc), src/base/ftver.rc, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.10.0/2.10.1/, s/2100/2101/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 23:1:17. * CMakeLists.txt (VERSION_PATCH): Set to 1. * include/freetype/fterrors.h (FT_Error_String): Fix C++ compilation. commit 7b1c7585d7ab929d9b29932d6697a22149162c13 Author: Alexei Podtelezhnikov <apodtele@gmail.com> Date: Wed Jun 26 20:18:00 2019 -0400 * src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Fix inequality.

The previous implementation is correct but it is too complex. The revised algorithm is based on the fact that each split moves the control points closer to the trisection points on the chord. The corresponding distances are good surrogates for the curve deviation from the straight line. This cubic flattening algorithm is somewhat similar to the conic algorithm based the distance from the control point to the middle of the chord. The cubic distances, however, decrease less predictably but are easy enough to calculate on each step. * src/smooth/ftgrays.c (gray_render_cubic): Replace the split condition. commit 80475edead39eb3e7305ebfd43c3fb03a04d372f Author: Alexei Podtelezhnikov <apodtele@gmail.com> Date: Fri Apr 26 21:53:00 2019 -0400 [smooth] Bithacks and cosmetics. * src/smooth/ftgrays.c (gray_record_cell, gray_set_cell, gray_hline, gray_render_conic, gray_convert_glyph_inner): Updated. commit 7a81b63abc2b3da0d7f0950f69377d2b3f54b0fb Author: Alexei Podtelezhnikov <apodtele@gmail.com> Date: Thu Apr 25 22:06:33 2019 -0400 Optimize Bézier bisections. * src/raster/ftraster.c (Split_Conic, Split_Cubic): Use shifts and refactor. * src/smooth/ftgrays.c (gray_split_conic, gray_split_cubic): Ditto. * src/base/ftstroke.c (ft_conic_split, ft_cubic_split): Ditto. * src/base/ftbbox.c (cubic_peak): Use shifts. commit 432bb50ff539e7672723dc9161e44046710a1334 Author: Alexei Podtelezhnikov <apodtele@gmail.com> Date: Tue Apr 23 21:51:42 2019 -0400 Clarify docs. commit 6abce2c2b04a14bd711d5d0fee3ba23e9612a747 Author: Werner Lemberg <wl@gnu.org> Date: Tue Apr 23 06:52:07 2019 +0200 * src/sfnt/ttcmap.c (tt_cmap12_next): Remove dead code.

Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected. Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>. * include/freetype/fttypes.h (FT_BOOL): Add a comparison against zero so that we always have a Boolean expression. */*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where possible. commit 0f122fef346af27ce469fa3e521bbde747fb741c Author: Alexei Podtelezhnikov <apodtele@gmail.com> Date: Sun Sep 23 21:46:26 2018 -0400 [bdf] Speed up charmap access.

For bitmap fonts, `FT_Load_Glyph' should either return an error or not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this case `FT_Load_Glyph' calls into the auto-hinter which calls back into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path (even though it doesn't have any path). It appears that the auto-hinter should not be called when the face doesn't have outlines. The current test for using the auto-hinter in `FT_Load_Glyph' checks if the driver supports scalable outlines, but not if the face supports scalable outlines. * src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have scalable outlines. commit c168cc3b1bf13e5f3ca77c238dcb204ea821c56d Author: Werner Lemberg <wl@gnu.org> Date: Fri Sep 21 11:09:27 2018 +0200 [raster] Fix disappearing vertical lines (#54589). * src/raster/ftraster.c (Vertical_Sweep_Span): Handle special case where both left and right outline exactly pass pixel centers. commit 493aa68f5c4cb2e659570809931539dc1987630c Author: Werner Lemberg <wl@gnu.org> Date: Fri Sep 21 08:32:22 2018 +0200 [base] Some comments. commit 2a9850c4fc2fd75021359346c9ffc7478f12d449 Author: Alexei Podtelezhnikov <apodtele@gmail.com> Date: Thu Sep 20 22:40:32 2018 -0400 * src/base/ftobjs.c (ft_glyphslot_reset_bimap): Tiny rounding tweak.

This commit enables OpenType's COLR/CPAL table handling; a typical application are color emojis that can be scaled to any size. If the color palette does not exist or is invalid, the rendering step rasterizes the outline instead. The current implementation assumes that the foreground is black. Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.

AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'. The Solaris Studio 12.1 through 12.5 compilers see the `-fvisibility=hidden' flag, but ignore it with a warning of: cc: Warning: Option -fvisibility=hidden passed to ld, if ld is invoked, ignored otherwise AC_LINK_IFELSE does the compile and then tries to link the result, at which point the Solaris linker will issue an error: ld: fatal: option '-fvisibility=hidden' is incompatible with building a dynamic executable If we don't use AC_LINK_IFELSE to catch the error, then configure will fail further tests which attempt to link, such as those testing dependencies like `libbz2'. Also, don't try adding `-fvisibility' if we have already added `-xldscope', just use one of them, since Sun Studio 12 and earlier compilers only issue a warning, and don't try passing through to the linker to generate an error, so AC_LINK_IFELSE doesn't catch them. Tested on Solaris 11.4 beta with compiler versions: Sun Studio 8 (Sun C 5.5) Sun Studio 10 (Sun C 5.7) Sun Studio 11 (Sun C 5.8) Sun Studio 12 (Sun C 5.9) Sun Studio 12.1 (Sun C 5.10) Oracle Solaris Studio 12.2 (Sun C 5.11) Oracle Solaris Studio 12.3 (Sun C 5.12) Oracle Solaris Studio 12.4 (Sun C 5.13) Oracle Developer Studio 12.5 (Sun C 5.14) Oracle Developer Studio 12.6 (Sun C 5.15) gcc 5.5.0 gcc 7.3.0 and verified the libfreetype.so.6 generated by each of those compilers exported the same set of symbols. * builds/unix/configure.raw: Implement it. commit e0015f7612cf07ff80561475321ce1f98c7c2b88 Author: Werner Lemberg <wl@gnu.org> Date: Tue May 8 11:51:16 2018 +0200 [autofit] Avoid potential SEGV if running out of memory.

+2020-09-21  David Turner  <david@freetype.org>
+
+	Add python script for building tarballs.
+
+	* scripts/make_distribution_archives.py: New file.
+
+	This standalone Python script should be equivalent to running `make
+	dist` with the Make-based build system, with the following minor
+	differences:
+
+	- Since `make distclean` doesn't always clean up `objs/` properly,
+	  `make dist` archives may contain some stale binaries like
+	  `objs/.libs/libfreetype.so.6` or others.
+
+	- `config.guess` and `config.sub` are not updated unless option
+	  `--gnu-config-dir=DIR` is used to specify the location of these
+	  files.
+
+	- Some bits of the auto-generated reference documentation may
+	  appear in slightly different order, probably due to issues related
+	  to mkdocs and docwriter.
+
+	As an example, the call
+
+	  scripts/make_distribution_archives.py /tmp/freetype2-dist
+
+	creates the following files under `/tmp/freetype2-dist`:
+
+	  freetype-<version>.tar.gz
+	  freetype-<version>.tar.xz
+	  ft<winversion>.zip
+
+2020-09-21  Werner Lemberg  <wl@gnu.org>

+	* scripts/extract_freetype_version.py: Fix regex typos.
+
+2020-09-21  David Turner  <david@freetype.org>
+
+	Add Meson build project file.
+
+	Example usage:
+
+	  # Configure Meson build in directory `build-meson` to generate
+	  # release binaries comparable to to the ones from the
+	  # autotools/make build system.
+	  meson setup build-meson \
+	        --prefix=/usr/local \
+	        --buildtype=debugoptimized \
+	        --strip \
+	        -Db_ndebug=true
+
+	  # After configuring the Meson build with the above command,
+	  # compile and install to `/usr/local/`; this includes a pkg-config
+	  # file.
+	  ninja -C build-meson install
+
+	  # Alternatively, compile and install to `/tmp/aa/usr/local/...`
+	  # for packaging.
+	  DESTDIR=/tmp/aa ninja -C build-meson install
+
+	  # Generate documentation under `build-meson/docs`.
+	  ninja -C build-meson docs
+
+	Library size comparison for stripped `libfreetype.so` generated by
+	all three build systems:
+
+	  - Default build (autotools + libtool): 712 KiB
+	  - CMake build (RelWithDebInfo):        712 KiB
+	  - Meson build:                         712 KiB
+
+
+	* meson.build: New top-level Meson build file for the library.
+
+	* meson_options.txt: New file.  It holds user-selectable options for
+	the build, which can be printed with `meson configure`, and selected
+	at `meson setup` or `meson --reconfigure` time with
+	`-D<option>=<value>`.
+
+	* scripts/parse_modules_cfg.py: A script invoked by `meson.build` to
+	parse `modules.cfg` and extract important information out of it
+	(i.e., the list of modules).
+
+	* scripts/process_ftoption_h.py: New script invoked by `meson.build`
+	to process the original `ftoption.h` file.  It enables or disables
+	configuration macro variables based on the available dependencies.
+	This is similar to what other build systems are using (i.e., Meson's
+	`configure_file()` command is not used here).
+
+	* scripts/extract_freetype_version.py: New script invoked by
+	`meson.build` to extract the FreeType version number from
+	`<freetype/freetype.h>`.
+
+	* scripts/extract_libtool_version.py: New script invoked by
+	`meson.build` to extract the libtool `revision_info` data from
+	`builds/unix/configure.raw`, and to generate the corresponding
+	shared library suffix.
+
+	* scripts/generate_reference_docs.py: New script invoked by
+	`meson.build` to generate the FreeType 2 reference documentation
+	(using the `docwriter` and `mkdocs` packages, which must be already
+	installed).

+
+	[woff2] Avoid too many calls to `FT_REALLOC'.

+	(pad4, store_loca, reconstruct_glyf, reconstruct_hmtx,
+	reconstruct_font): Update parameters to accept `sfnt_size'.
+
+	(woff2_open_font): Add variable `sfnt_size'.  Use WOFF2 header field
+	`totalSfntSize' as initial reference (if value makes sense) and
+	allocate `totalSfntSize' bytes for the sfnt stream.  `write_buf'
+	handles reallocation if and when required.  Also resize the stream

+	more refining and better memory management.

+	(reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte**
+	sfnt_bytes'.  This has been done because we reallocate memory to

+
+	[psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580).
+
+	As originally intended, a Type 1 SEAC charstring would be used for
+	an accented glyph (like `acaron' or `uumlaut'), where the advance
+	width of the SEAC glyph is the same as that of the `base' glyph
+	(like `a' or `u').  In this case it is not uncommon for the SEAC
+	glyph to not use an (H)SBW opcode of its own but to rely on the
+	value from the base glyph.
+
+	However, out-of-spec fonts also use SEAC glyphs for ligatures (like
+	`oe' or `fi'), and in those cases the overall advance width is
+	greater than that of the `base' glyph.  For this reason we have to
+	allow that the SEAC glyph can have an (H)SBW value of its own, and
+	if it has, retain this value, rather than the one from the base
+	glyph.
+
+	* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>:
+	Implement it.

+
+	[smooth] Simplify cubic Bézier flattening.
+
+	The previous implementation is correct but it is too complex.
+	The revised algorithm is based on the fact that each split moves
+	the control points closer to the trisection points on the chord.
+	The corresponding distances are good surrogates for the curve
+	deviation from the straight line.
+
+	This cubic flattening algorithm is somewhat similar to the conic
+	algorithm based the distance from the control point to the middle of
+	the chord.  The cubic distances, however, decrease less predictably
+	but are easy enough to calculate on each step.
+
+	The new algorithm produces slightly larger number of splits, which is
+	compensated by its simplicity.  The overall rendering performance is
+	improved by 1-2%.  The larger number of splits does not necessarily
+	result in higher quality, which stays comparable.

+
+	[psaux] Fix use of uninitialized memory (#55832).
+
+	* src/psaux/psintrp.c (cf2_interpT2CharString): The call to
+	`cf2_arrstack_setCount' may fail because the allocator ran out of

-	[cff] Fix family name logic of pure CFF fontdata (#52056).
+	Unbreak CMake Windows installation
 
-	1. If `FamilyName' is present in the CFF font, use this for
-	   FT_Face's `family_name'.
-	2. Otherwise, use the face name and chop off any subset prefix.
-	3. If at this point FT_Face's `family_name' is set, use this
-	   together with the full name to determine the style.
-	4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.
-	5. If we don't have a valid style, use "Regular".
+	* CMakeLists.txt: Generate ftconfig.h on non-UNIX.
 
-	Previously, FT_Face's `family_name' entry for pure CFF fontdata
-	nearly always was the fontname itself, instead of the `FamilyName'
-	entry in the CFF font (assuming there is one).

+
+	Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC).
+
+	CMake will no longer look for a C++ compiler.
+
+	Library and .so version now match the Autotools build.
+
+	Comments in the build file and informational messages now use platform
+	agnostic example commands.
+
+	ftoption.h and ftconfig.h are written directly without a redundant `-new'
+	copy.
+
+	External dependencies are expressed as option()s and will turn up as such
+	in cmake-gui.
+
+	Internal: Properties such as dependencies and include directories are now
+	privately set on the freetype library instead of globally.
+
+	The CPack definitions have been cleaned up, the `make dist' has been
+	removed. Source packages generated with CPack don't contain Autotools
+	files and aren't used by the maintainers anyway.
+
+	On Windows, src/base/ftver.rc is compiled to decorate the library with
+	version and copyright information.
+
+	A pkg-config file is now generated and installed.

+	[psaux] Fix Type 1 glyphs with too many stem hints.
+
+	According to the CFF specification, charstrings can have up to 96 stem

+
+	Use Adobe hinting engine for `light' hinting of both CFF and Type 1.
+
+	Since Ewald Hew factored the Adobe hinting engine out of the CFF
+	driver code, we can now use it on Type 1 (and CID) font formats, as
+	both have the same hinting philosophy.
+
+	This change activates the Adobe hinter when in LIGHT mode, and
+	therefore always unless explicitly asking for the auto-hinter.  This
+	makes LIGHT behavior consistent with CFF fonts.  As of this commit,
+	the hinting engine table looks as follows.

+
+	[cff, truetype] Adjust behaviour of named instances.
+
+	This commit completely separates the interaction between named

+	[cff] Fix family name logic of pure CFF fontdata (#52056).
+
+	1. If `FamilyName' is present in the CFF font, use this for
+	   FT_Face's `family_name'.
+	2. Otherwise, use the face name and chop off any subset prefix.
+	3. If at this point FT_Face's `family_name' is set, use this
+	   together with the full name to determine the style.
+	4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.
+	5. If we don't have a valid style, use "Regular".
+
+	Previously, FT_Face's `family_name' entry for pure CFF fontdata
+	nearly always was the fontname itself, instead of the `FamilyName'
+	entry in the CFF font (assuming there is one).
+
+	* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.
+
+2017-09-18  Alexei Podtelezhnikov  <apodtele@gmail.com>

+# SYNOPSIS
+#
+#   AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
+#
+# DESCRIPTION
+#
+#   This macro compares two version strings. Due to the various number of
+#   minor-version numbers that can exist, and the fact that string
+#   comparisons are not compatible with numeric comparisons, this is not
+#   necessarily trivial to do in a autoconf script. This macro makes doing
+#   these comparisons easy.
+#
+#   The six basic comparisons are available, as well as checking equality
+#   limited to a certain number of minor-version levels.
+#
+#   The operator OP determines what type of comparison to do, and can be one
+#   of:
+#
+#    eq  - equal (test A == B)
+#    ne  - not equal (test A != B)
+#    le  - less than or equal (test A <= B)
+#    ge  - greater than or equal (test A >= B)
+#    lt  - less than (test A < B)
+#    gt  - greater than (test A > B)
+#
+#   Additionally, the eq and ne operator can have a number after it to limit
+#   the test to that number of minor versions.
+#
+#    eq0 - equal up to the length of the shorter version
+#    ne0 - not equal up to the length of the shorter version
+#    eqN - equal up to N sub-version levels
+#    neN - not equal up to N sub-version levels
+#
+#   When the condition is true, shell commands ACTION-IF-TRUE are run,
+#   otherwise shell commands ACTION-IF-FALSE are run. The environment
+#   variable 'ax_compare_version' is always set to either 'true' or 'false'
+#   as well.
+#
+#   Examples:
+#
+#     AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8])
+#     AX_COMPARE_VERSION([3.15],[lt],[3.15.8])
+#
+#   would both be true.
+#
+#     AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8])
+#     AX_COMPARE_VERSION([3.15],[gt],[3.15.8])
+#
+#   would both be false.
+#
+#     AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8])
+#
+#   would be true because it is only comparing two minor versions.
+#
+#     AX_COMPARE_VERSION([3.15.7],[eq0],[3.15])
+#
+#   would be true because it is only comparing the lesser number of minor
+#   versions of the two values.
+#
+#   Note: The characters that separate the version numbers do not matter. An
+#   empty string is the same as version 0. OP is evaluated by autoconf, not
+#   configure, so must be a string, not a variable.
+#
+#   The author would like to acknowledge Guido Draheim whose advice about
+#   the m4_case and m4_ifvaln functions make this macro only include the
+#   portions necessary to perform the specific comparison specified by the
+#   OP argument in the final configure script.

+# DESCRIPTION
+#
+#   Makes sure that python supports the version indicated. If true the shell
+#   commands in ACTION-IF-TRUE are executed. If not the shell commands in
+#   ACTION-IF-FALSE are run. Note if $PYTHON is not set (for example by
+#   running AC_CHECK_PROG or AC_PATH_PROG) the macro will fail.
+#
+#   Example:
+#
+#     AC_PATH_PROG([PYTHON],[python])
+#     AX_PROG_PYTHON_VERSION([2.4.4],[ ... ],[ ... ])
+#
+#   This will check to make sure that the python you have supports at least
+#   version 2.4.4.
+#
+#   NOTE: This macro uses the $PYTHON variable to perform the check.
+#   AX_WITH_PYTHON can be used to set that variable prior to running this
+#   macro. The $PYTHON_VERSION variable will be valorized with the detected
+#   version.

-  FreeType&nbsp;2 Project Files for VS.NET&nbsp;2005
-</h1>
-
-<p>This directory contains project files for Visual C++, named
-<tt>freetype.vcproj</tt>, and Visual Studio, called <tt>freetype.sln</tt>.  It
-compiles the following libraries from the FreeType 2.9.1 sources:</p>
-
-<ul>
-  <pre>
-    freetype291.lib     - release build; single threaded
-    freetype291_D.lib   - debug build;   single threaded
-    freetype291MT.lib   - release build; multi-threaded
-    freetype291MT_D.lib - debug build;   multi-threaded</pre>
-</ul>
-
-<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
-archives are already stored this way, so no further action is required.  If
-you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
-tool to convert the line endings.  For example, with <a
-href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
-file smart CR/LF Conversion</em> option.  Alternatively, you may consider
-using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
-around, which specifically deal with this particular problem.
-
-<p>Build directories are placed in the top-level <tt>objs</tt>
-directory.</p>

-  FreeType&nbsp;2 Project Files for VS.NET&nbsp;2008
-</h1>
-
-<p>This directory contains project files for Visual C++, named
-<tt>freetype.vcproj</tt>, and Visual Studio, called <tt>freetype.sln</tt>.  It
-compiles the following libraries from the FreeType 2.9.1 sources:</p>
-
-<ul>
-  <pre>
-    freetype291.lib     - release build; single threaded
-    freetype291_D.lib   - debug build;   single threaded
-    freetype291MT.lib   - release build; multi-threaded
-    freetype291MT_D.lib - debug build;   multi-threaded</pre>
-</ul>
-
-<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
-archives are already stored this way, so no further action is required.  If
-you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
-tool to convert the line endings.  For example, with <a
-href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
-file smart CR/LF Conversion</em> option.  Alternatively, you may consider
-using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
-around, which specifically deal with this particular problem.
-
-<p>Build directories are placed in the top-level <tt>objs</tt>
-directory.</p>

+CHANGES BETWEEN 2.10.3 and 2.10.4
+
+  I. IMPORTANT BUG FIXES
+
+  - A heap buffer overflow has been found  in the handling of embedded
+    PNG bitmaps, introduced in FreeType version 2.6.
+
+      https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-15999
+
+    If you  use option  FT_CONFIG_OPTION_USE_PNG  you  should  upgrade
+    immediately.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.10.2 and 2.10.3
+
+  I. IMPORTANT CHANGES
+
+  - New flag `FT_OUTLINE_OVERLAP'.  If set, make the smooth rasterizer
+    do  4x4 oversampling  to  mitigate artifacts  in pixels  partially
+    covered  by  overlapping  contours.    Note  that  this  at  least
+    quadruples the rendering time.
+
+    If  a  glyph  in  a  TrueType font  has  the  `OVERLAP_SIMPLE'  or
+    `OVERLAP_COMPOUND'  bit set,  FreeType automatically  selects this
+    rendering mode.
+
+
+  II. MISCELLANEOUS
+
+  - Using the  arcane method of  including FreeType header  files with
+    macros like  `FT_FREETYPE_H' is no longer  mandatory (but retained
+    as an optional feature for backward compatibility).
+
+  - Support for  building the library  with Meson.  Building  the demo
+    programs with Meson will follow in a forthcoming release.
+
+  - Minor improvements to the B/W rasterizer.
+
+  - Auto-hinter support for Medefaidrin script.
+
+  - Fix various  memory leaks (mainly  for CFF) and other  issues that
+    might cause crashes in rare circumstances.
+
+  - Jam support has been removed.
+
+  - In  `ftview', custom  LCD  filter values  are  now normalized  and
+    balanced.  Unorthodox filters are still available through the `-L'
+    command line option.
+
+  - The GUI demo programs can now be resized.
+
+  - Demo programs that accept command  line option `-k' can now handle
+    function keys, too.  The  corresponding character codes start with
+    0xF1.  As  an example, the  POSIX shell syntax (accepted  by bash,
+    ksh, and zsh)
+
+      -k $'\xF3q'
+
+    emulates the pressing of function key `F3' followed by key `q'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.10.1 and 2.10.2
+
+  I. IMPORTANT CHANGES
+
+  - Support  of  WOFF2  fonts.   This  code  contribution  was  Nikhil
+    Ramakrishnan's GSoC 2019 project.
+
+
+  II. MISCELLANEOUS
+
+  - Function  `FT_Get_Var_Axis_Flags' returned random data for  Type 1
+    MM fonts.
+
+  - Type 1 fonts with non-integer metrics are now supported by the new
+    (CFF) engine introduced in FreeType 2.9.
+
+  - Drop  support  for Python 2 in Freetype's API reference  generator
+    `docwriter'  (Python >= 3.5 is required for targets  `make refdoc'
+    and `make refdoc-venv').
+
+  - Auto-hinter support for Hanifi Rohingya.
+
+  - Document the `FT2_KEEP_ALIVE' debugging environment variable.
+
+  - The Visual C++ (and Visual C)  project files for Windows builds no
+    longer generate libraries that contain the FreeType version in its
+    filenames.   Instead,  a  resource  file gets  used  to  make  the
+    libraries contain the corresponding information.
+
+  - The next release will remove Jam build support.
+
+  - The  `ftbench'  demo  program  has  a new  test  for  testing  the
+    `FT_Glyph_Stroke' functionality.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.10.0 and 2.10.1
+
+  I. IMPORTANT BUG FIXES
+
+  - The bytecode hinting of OpenType variation fonts was flawed, since
+    the data in the `CVAR' table wasn't correctly applied.
+
+
+  II. MISCELLANEOUS
+
+  - Auto-hinter support for Mongolian.
+
+  - For distribution,  `.tar.bz2' packages are replaced with `.tar.xz'
+    bundles.
+
+  - The handling of  the default character in PCF fonts as  introduced
+    in version 2.10.0 was partially broken, causing premature abortion
+    of charmap iteration for many fonts.
+
+  - If  `FT_Set_Named_Instance' was  called  with  the same  arguments
+    twice in a row, the function  returned an incorrect error code the
+    second time.
+
+  - Direct   rendering   using  FT_RASTER_FLAG_DIRECT   crashed   (bug
+    introduced in version 2.10.0).
+
+  - Increased  precision  while  computing  OpenType  font   variation
+    instances.
+
+  - The  flattening  algorithm of  cubic  Bezier  curves was  slightly
+    changed to make  it faster.  This can cause  very subtle rendering
+    changes, which aren't noticeable by the eye, however.
+
+  - The  auto-hinter  now  disables hinting  if there  are blue  zones
+    defined for a `style' (i.e., a certain combination of a script and
+    its related typographic features) but the font doesn't contain any
+    characters needed to set up at least one blue zone.
+
+  - The `ftmulti' demo program now  supports multiple hidden axes with
+    the same name tag.
+
+  - `ftview', `ftstring', and `ftgrid' got  a `-k' command line option
+    to emulate a sequence of keystrokes at start-up.
+
+  - `ftview', `ftstring', and `ftgrid' now support screen dumping to a
+    PNG file.
+
+  - The bytecode debugger, `ttdebug',  now supports variation TrueType
+    fonts; a variation font instance can be selected with the new `-d'
+    command line option.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.9.1 and 2.10.0
+
+  I. IMPORTANT CHANGES
+
+    - A bunch  of new functions has  been added to access  and process
+      COLR/CPAL data of OpenType fonts with color-layered glyphs.
+
+        FT_Palette_Data_Get
+          Retrieve color palette data.
+        FT_Palette_Select
+          Select and activate a color palette for color-layered
+          glyphs.
+        FT_Palette_Set_Foreground_Color
+          Set text foreground color for palette index 0xFFFF.
+
+        FT_Get_Color_Glyph_Layer
+          Get color layers for a given glyph (using an interator
+          object).
+
+        FT_Bitmap_Blend
+          Blend one bitmap onto another with a given color.
+
+    - An   experimental  feature   is   the  new   behaviour  of   the
+      `FT_LOAD_COLOR' load  flag for color-layered  glyphs: Internally
+      it  sets a  flag so  that  if `FT_Render_Glyph'  is called  with
+      `FT_RENDER_MODE_NORMAL'      (or       `FT_Load_Glyph'      with
+      `FT_LOAD_RENDER'), a default blending  of the color glyph layers
+      will happen automatically for convenience.
+
+    - As  a   GSoC  2018   project,  Nikhil   Ramakrishnan  completely
+      overhauled and modernized the API reference.
+
+
+  II. MISCELLANEOUS
+
+    - The  logic for  computing  the global  ascender, descender,  and
+      height  of  OpenType  fonts   has  been  slightly  adjusted  for
+      consistency.
+
+      . If the `useTypoMetrics' flag (i.e., bit 7 in the `fsSelection'
+        field) in the  `OS/2' table is set, use the  `sTypo' fields in
+        `OS/2' unconditionally.
+      . Otherwise use  the metrics data from the `hhea'  table (if not
+        zero).
+      . Otherwise use the `sTypo' fields from the `OS/2' table (if not
+        zero).
+      . Otherwise use the `usWin' data from the `OS/2' table as a last
+        resort.
+
+      Variable fonts will apply the `MVAR' deltas to whichever metrics
+      were picked.
+
+    - `TT_Set_MM_Blend' could  fail if  call repeatedly with  the same
+      arguments.
+
+    - The precision  of handling  deltas in  Variation Fonts  has been
+      increased.  The  problem did only show  up with multidimensional
+      designspaces.
+
+    - New function `FT_Library_SetLcdGeometry' to  set up the geometry
+      of LCD subpixels.
+
+    - FreeType now uses the `defaultChar' property of PCF fonts to set
+      the  glyph for  the undefined  character  at glyph  index 0  (as
+      FreeType already does for all other supported font formats).  As
+      a consequence,  the order of  glyphs of  a PCF font  if accessed
+      with  FreeType  can  be   different  now  compared  to  previous
+      versions.
+
+      This change doesn't affect PCF font access with cmaps.
+
+    - `FT_Select_Charmap' has  been changed  to allow  parameter value
+      `FT_ENCODING_NONE', which is valid for BDF, PCF, and Windows FNT
+      formats to  access built-in cmaps  that don't have  a predefined
+      `FT_Encoding' value.
+
+    - A previously  reserved field in the  `FT_GlyphSlotRec' structure
+      now holds the glyph index.
+
+    - On Win32 platforms,  the use of `_DLL' to build  the library has
+      been replaced with `DLL_EXPORT' and `DLL_IMPORT'.
+
+    - The usual round  of fuzzer bug fixes to  better reject malformed
+      fonts.
+
+    - `FT_Outline_New_Internal'  and  `FT_Outline_Done_Internal'  have
+      been removed.  These two functions were public by oversight only
+      and were never documented.
+
+    - A new  function `FT_Error_String' returns descriptions  of error
+      codes if  configuration macro  FT_CONFIG_OPTION_ERROR_STRINGS is
+      defined.
+
+    - `FT_Set_MM_WeightVector'  and  `FT_Get_MM_WeightVector' are  new
+      functions limited to Adobe MultiMaster fonts to directly set and
+      get the weight vector.
+
+    - Support for Position Independent Code as needed by  systems that
+      prohibit  automatic  address  fixups,  such  as BREW,  has  been
+      removed.  [Compilation with modern compilers that use flags like
+      `-fPIC' or `-fPIE' is not affected.]
+
+    - The  `ftdump' demo  program has  new  options `-c'  and `-C'  to
+      display charmaps  in compact and detailed  format, respectively.
+      Option `-V' has been removed.
+
+    - The `ftview', `ftstring',  and `ftgrid' demo programs  use a new
+      command line option `-d' to  specify the program window's width,
+      height, and color depth.
+
+    - The `ftview' demo program now  displays red boxes for zero-width
+      glyphs.
+
+    - `ftglyph'   has   limited   support  to   display   fonts   with
+      color-layered glyphs.  This will be improved later on.
+
+    - `ftgrid' can now display bitmap fonts also.
+
+    - The `ttdebug'  demo program has  a new  option `-f' to  select a
+      member of a TrueType collection (TTC).
+
+    - Other various improvements to the demo programs.

+Introduction
+------------
+
+Documentation is an extremely important part of any project, and it
+helps a lot if it uses consistent syntax and layout.
+
+The documentation for the FreeType library is maintained in header
+files in the `include/` directory in the form of code comments.  These
+comments are extracted and organized by 'docwriter' (previously
+'docmaker').  The generated docs can be viewed in the
+`docs/reference/site/` directory after running `make refdoc`.
+
+Documentation comments follow a specific structure and format as
+described below.
+
+
+Documentation Structure
+-----------------------
+
+The documentation is divided into multiple chapters, which contain
+sections relevant to it.  The chapter details and sections contained
+in them are listed in `include/freetype/ftchapters.h`.  Any unlisted
+section is added to the 'Miscellaneous' chapter.
+
+Sections may contain sub-sections which consist of properties,
+enumerations, and other data types.
+
+
+Comment Blocks
+--------------
+
+Documentation blocks follow a specific format:
+
+    /***************************** (should end on column 77)
+     *
+     *                             (1 asterisk, 1 space, then content)
+     *
+     */                            (end of block)
+
+To make 'docwriter' recognize a comment block, there must be at least
+two asterisks in the first line.  As a consequence, you should change
+the second asterisk to something else if you want to prevent a comment
+block being handled by 'docwriter' (for example, change `/****/` to
+`/*#**/`).
+
+
+Markup Tags
+-----------
+
+Markup tags are used to indicate what comes next.  The syntax for a
+tag is:
+
+    @foo:
+
+An `@`, followed by the tag, and then `:`.
+
+
+Reserved Tags
+-------------
+
+There are some keywords that have a special meaning to docwriter.
+As a convention, all keywords are written in lowercase.
+
+* `chapter`: Defines a chapter.  Usually the title with underscores.
+* `sections`: List of sections in the chapter, in order.
+* `section`: Defines the start or continuation of a section.
+* `title`: Title for a chapter or section.  May contain spaces.
+* `abstract`: The abstract for a section, visible in the Table of
+              Contents (TOC).
+* `description`: Detailed description of a tag (except chapters),
+                 shown as synopsis.
+* `values`: A list of 'values' for the tag.  These values are used for
+            cross-referencing.
+
+
+Other Tags
+----------
+
+Except the ones given above, any other tags will be added as a part of
+a subsection.  All tags are lowercase by convention.
+
+
+Public Header Definitions
+-------------------------
+
+The public headers for FreeType have their names defined in
+`include/freetype/config/ftheader.h`.  Any new public header file must
+be defined in this file, in the following format:
+
+    #define FT_NEWNAME_H  <freetype/newname.h>
+
+Where `newname` is the name of the header file.
+
+This macro is combined with the file location of a sub-section and
+printed with the object.
+
+
+Note on code blocks captured after comments
+-------------------------------------------
+
+All non-documentation lines after a documentation comment block are
+captured to be displayed as the code for the sub-section.  To stop
+collection, a line with `/* */` should be added.
+
+
+General Formatting Conventions
+------------------------------
+
+* Use two spaces after a full stop ending a sentence.
+* Use appropriate uppercasing in titles.  Refer
+
+  https://english.stackexchange.com/a/34
+
+  for more information.
+* Do not add trailing parentheses when citing a C function.
+
+
+Markdown Usage
+--------------
+
+All tags, except the ones that define the name and title for a block
+support markdown in them.  Docwriter uses a markdown parser that
+follows rules given in John Gruber's markdown guide:
+
+  https://daringfireball.net/projects/markdown/syntax
+
+with a few exceptions and extensions, detailed below.  This may also
+be referred to as the **FreeType Flavored Markdown**.
+
+
+Headers
+-------
+
+Markdown headers should not be used directly, because these are added
+based on section titles, sub-section names, and tags.  However, if a
+header needs to be added, note the following correspondence to HTML tags:
+
+* Section title on top of the page is `H1`.
+* Sub-section titles are `H2`.
+* Parts of sub-sections are `H4`.
+* Any header added will be visible in the Table of Contents (TOC) of
+  the page.
+
+
+Emphasis
+--------
+
+* Use `_underscores_` for italics.
+* Use `**double asterisks**` for bold.
+
+Although the other notations (double underscore for bold, single
+asterisk for italics) are supported, it is recommended to use the
+above for consistency.
+
+Note that there may be cases where having two asterisks or underscores
+in a line may lead to text being picked up as italics or bold.
+Although unintentional, this is correct markdown behavior. 
+
+For inline code, wrap the sequence with backticks (see below).  This
+renders symbols correctly without modifications.  If a symbol is
+absolutely required outside of an inline code block or code sequence,
+escape it with a backslash (like `\*` or `\_`).
+
+
+Lists
+-----
+
+Unordered lists can be created with asterisks:
+
+    * Unordered list items can use asterisks.
+    * Another list item.
+
+Ordered lists start with numbers:
+
+    1. This is an ordered list item.
+    2. Brackets after numbers won't work.
+
+To continue a list over multiple paragraphs, indent them with at least
+four spaces.  For example:
+
+    1.  Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+        Aliquam hendrerit mi posuere lectus.  Vestibulum enim wisi,
+        viverra nec, fringilla in, laoreet vitae, risus.
+
+        Donec sit amet nisl.  Aliquam semper ipsum sit amet velit.
+        Suspendisse id sem consectetuer libero luctus adipiscing.
+
+    2.  This is the second list item.
+
+    This paragraph is not a part of the list.
+
+More information on lists in markdown is available at
+
+  https://daringfireball.net/projects/markdown/syntax#list
+
+
+Cross-references
+----------------
+
+Other sub-sections can be linked with the `@` symbol:
+
+    @description:
+      While FreeType's CFF driver doesn't expose API functions by
+      itself, it is possible to control its behaviour with 
+      @FT_Property_Set and @FT_Property_Get.
+
+If a field in the `values` table of another sub-section is linked, the
+link leads to its parent sub-section.
+
+
+Links and Images
+----------------
+
+All URLs are converted to links in the HTML documentation.
+
+Markdown syntax for links and images are fully supported.
+
+
+Inline Code
+-----------
+
+To indicate a span of code, wrap it with backtick quotes (`` ` ``):
+
+    Use the `printf()` function.
+
+Cross-references, markdown, and html styling do not work in inline code
+sequences.
+
+
+Code and Syntax Highlighting
+----------------------------
+
+Blocks of code are fenced by lines with three back-ticks `` ``` ``
+followed by the language name, if any (used for syntax highlighting),
+as demonstrated in the following example.
+
+    ```c
+      x = y + z;
+      if ( zookoo == 2 )
+      {
+        foobar();
+      }
+    ```
+
+Note that the indentation of the opening line and the closing line
+must be exactly the same.  The code sequence itself should have a
+larger indentation than the surrounding back-ticks.
+
+Like inline code, markdown and html styling is *not* supported inside
+code blocks.
+
+
+Tables
+------
+
+Tables are used to list values, input, and other fields.  The FreeType
+Flavored Markdown adopts a simple approach to tables with two columns,
+or field definition tables.
+
+Field definition names may contain alphanumeric, underscore, and the
+`.` characters.  This is followed by `::`.  The following lines are
+the second column of the table.  A field definition ends with the
+start of another field definition, or a markup tag.
+
+    @Input:
+      pathname ::
+        A path to the font file.
+
+      face_index ::
+        See @FT_Open_Face for a detailed description of this
+        parameter.
+
+
+Non-breaking Space
+------------------
+
+A tilde can be used to create a non-breaking space.  The example
+
+    The encoding value~0 is reserved.
+
+is converted to
+
+    The encoding value&nbsp;0 is reserved.

+After saying `make refdoc' or `make refdoc-venv' the `reference/' directory

+
+There are two ways to generate the documentation:
+
+1. Using `make refdoc':
+
+    - Ensure `python' and `pip' are available.
+    - Install pip package `docwriter' with `pip install --user docwriter'.
+    - Make target with `make refdoc'.
+    - This target can be run offline once required packages are installed.

+    - Make target with `make refdoc-venv'.
+    - This may or may not require internet access every time depending on

+
+This also works with Jam: Just type `jam refdoc' in the main directory.
+
+Some troubleshooting tips:
+
+* Regularly run `pip install --upgrade docwriter' to check for updates which

+* `Docwriter' does not support Python 2.  Ensure that Python >= 3.5 is

+
+* Ensure that `docwriter' is installed in the same Python target that

+   *     #include FT_MULTIPLE_MASTERS_H
+   *     #include FT_GLYPH_H

+   * @enum:
+   *   FT_Encoding
+   *
+   * @description:
+   *   An enumeration to specify character sets supported by charmaps.  Used
+   *   in the @FT_Select_Charmap API function.
+   *
+   * @note:
+   *   Despite the name, this enumeration lists specific character
+   *   repertories (i.e., charsets), and not text encoding methods (e.g.,
+   *   UTF-8, UTF-16, etc.).
+   *
+   *   Other encodings might be defined in the future.
+   *
+   * @values:
+   *   FT_ENCODING_NONE ::
+   *     The encoding value~0 is reserved for all formats except BDF, PCF,
+   *     and Windows FNT; see below for more information.
+   *
+   *   FT_ENCODING_UNICODE ::
+   *     The Unicode character set.  This value covers all versions of the
+   *     Unicode repertoire, including ASCII and Latin-1.  Most fonts include
+   *     a Unicode charmap, but not all of them.
+   *
+   *     For example, if you want to access Unicode value U+1F028 (and the
+   *     font contains it), use value 0x1F028 as the input value for
+   *     @FT_Get_Char_Index.
+   *
+   *   FT_ENCODING_MS_SYMBOL ::
+   *     Microsoft Symbol encoding, used to encode mathematical symbols and
+   *     wingdings.  For more information, see
+   *     'https://www.microsoft.com/typography/otspec/recom.htm#non-standard-symbol-fonts',
+   *     'http://www.kostis.net/charsets/symbol.htm', and
+   *     'http://www.kostis.net/charsets/wingding.htm'.
+   *
+   *     This encoding uses character codes from the PUA (Private Unicode
+   *     Area) in the range U+F020-U+F0FF.
+   *
+   *   FT_ENCODING_SJIS ::
+   *     Shift JIS encoding for Japanese.  More info at
+   *     'https://en.wikipedia.org/wiki/Shift_JIS'.  See note on multi-byte
+   *     encodings below.
+   *
+   *   FT_ENCODING_PRC ::
+   *     Corresponds to encoding systems mainly for Simplified Chinese as
+   *     used in People's Republic of China (PRC).  The encoding layout is
+   *     based on GB~2312 and its supersets GBK and GB~18030.
+   *
+   *   FT_ENCODING_BIG5 ::
+   *     Corresponds to an encoding system for Traditional Chinese as used in
+   *     Taiwan and Hong Kong.
+   *
+   *   FT_ENCODING_WANSUNG ::
+   *     Corresponds to the Korean encoding system known as Extended Wansung
+   *     (MS Windows code page 949).  For more information see
+   *     'https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WindowsBestFit/bestfit949.txt'.
+   *
+   *   FT_ENCODING_JOHAB ::
+   *     The Korean standard character set (KS~C 5601-1992), which
+   *     corresponds to MS Windows code page 1361.  This character set
+   *     includes all possible Hangul character combinations.
+   *
+   *   FT_ENCODING_ADOBE_LATIN_1 ::
+   *     Corresponds to a Latin-1 encoding as defined in a Type~1 PostScript
+   *     font.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_ADOBE_STANDARD ::
+   *     Adobe Standard encoding, as found in Type~1, CFF, and OpenType/CFF
+   *     fonts.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_ADOBE_EXPERT ::
+   *     Adobe Expert encoding, as found in Type~1, CFF, and OpenType/CFF
+   *     fonts.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_ADOBE_CUSTOM ::
+   *     Corresponds to a custom encoding, as found in Type~1, CFF, and
+   *     OpenType/CFF fonts.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_APPLE_ROMAN ::
+   *     Apple roman encoding.  Many TrueType and OpenType fonts contain a
+   *     charmap for this 8-bit encoding, since older versions of Mac OS are
+   *     able to use it.
+   *
+   *   FT_ENCODING_OLD_LATIN_2 ::
+   *     This value is deprecated and was neither used nor reported by
+   *     FreeType.  Don't use or test for it.
+   *
+   *   FT_ENCODING_MS_SJIS ::
+   *     Same as FT_ENCODING_SJIS.  Deprecated.
+   *
+   *   FT_ENCODING_MS_GB2312 ::
+   *     Same as FT_ENCODING_PRC.  Deprecated.

+   *     Same as FT_ENCODING_JOHAB.  Deprecated.
+   *
+   * @note:
+   *   By default, FreeType enables a Unicode charmap and tags it with
+   *   `FT_ENCODING_UNICODE` when it is either provided or can be generated
+   *   from PostScript glyph name dictionaries in the font file.  All other
+   *   encodings are considered legacy and tagged only if explicitly defined

+   *
+   *   `FT_ENCODING_NONE` is set by the BDF and PCF drivers if the charmap is
+   *   neither Unicode nor ISO-8859-1 (otherwise it is set to
+   *   `FT_ENCODING_UNICODE`).  Use @FT_Get_BDF_Charset_ID to find out which
+   *   encoding is really present.  If, for example, the `cs_registry` field
+   *   is 'KOI8' and the `cs_encoding` field is 'R', the font is encoded in
+   *   KOI8-R.
+   *
+   *   `FT_ENCODING_NONE` is always set (with a single exception) by the
+   *   winfonts driver.  Use @FT_Get_WinFNT_Header and examine the `charset`
+   *   field of the @FT_WinFNT_HeaderRec structure to find out which encoding
+   *   is really present.  For example, @FT_WinFNT_ID_CP1251 (204) means
+   *   Windows code page 1251 (for Russian).
+   *
+   *   `FT_ENCODING_NONE` is set if `platform_id` is @TT_PLATFORM_MACINTOSH
+   *   and `encoding_id` is not `TT_MAC_ID_ROMAN` (otherwise it is set to

+   * @struct:
+   *   FT_FaceRec
+   *
+   * @description:
+   *   FreeType root face class structure.  A face object models a typeface
+   *   in a font file.
+   *
+   * @fields:
+   *   num_faces ::
+   *     The number of faces in the font file.  Some font formats can have
+   *     multiple faces in a single font file.
+   *
+   *   face_index ::
+   *     This field holds two different values.  Bits 0-15 are the index of
+   *     the face in the font file (starting with value~0).  They are set
+   *     to~0 if there is only one face in the font file.
+   *
+   *     [Since 2.6.1] Bits 16-30 are relevant to GX and OpenType variation
+   *     fonts only, holding the named instance index for the current face
+   *     index (starting with value~1; value~0 indicates font access without
+   *     a named instance).  For non-variation fonts, bits 16-30 are ignored.
+   *     If we have the third named instance of face~4, say, `face_index` is
+   *     set to 0x00030004.
+   *
+   *     Bit 31 is always zero (this is, `face_index` is always a positive
+   *     value).
+   *
+   *     [Since 2.9] Changing the design coordinates with
+   *     @FT_Set_Var_Design_Coordinates or @FT_Set_Var_Blend_Coordinates does
+   *     not influence the named instance index value (only
+   *     @FT_Set_Named_Instance does that).
+   *
+   *   face_flags ::
+   *     A set of bit flags that give important information about the face;
+   *     see @FT_FACE_FLAG_XXX for the details.
+   *
+   *   style_flags ::
+   *     The lower 16~bits contain a set of bit flags indicating the style of
+   *     the face; see @FT_STYLE_FLAG_XXX for the details.
+   *
+   *     [Since 2.6.1] Bits 16-30 hold the number of named instances
+   *     available for the current face if we have a GX or OpenType variation
+   *     (sub)font.  Bit 31 is always zero (this is, `style_flags` is always
+   *     a positive value).  Note that a variation font has always at least
+   *     one named instance, namely the default instance.
+   *
+   *   num_glyphs ::
+   *     The number of glyphs in the face.  If the face is scalable and has
+   *     sbits (see `num_fixed_sizes`), it is set to the number of outline
+   *     glyphs.
+   *
+   *     For CID-keyed fonts (not in an SFNT wrapper) this value gives the
+   *     highest CID used in the font.
+   *
+   *   family_name ::
+   *     The face's family name.  This is an ASCII string, usually in
+   *     English, that describes the typeface's family (like 'Times New
+   *     Roman', 'Bodoni', 'Garamond', etc).  This is a least common
+   *     denominator used to list fonts.  Some formats (TrueType & OpenType)
+   *     provide localized and Unicode versions of this string.  Applications
+   *     should use the format-specific interface to access them.  Can be
+   *     `NULL` (e.g., in fonts embedded in a PDF file).
+   *
+   *     In case the font doesn't provide a specific family name entry,
+   *     FreeType tries to synthesize one, deriving it from other name
+   *     entries.
+   *
+   *   style_name ::
+   *     The face's style name.  This is an ASCII string, usually in English,
+   *     that describes the typeface's style (like 'Italic', 'Bold',
+   *     'Condensed', etc).  Not all font formats provide a style name, so
+   *     this field is optional, and can be set to `NULL`.  As for
+   *     `family_name`, some formats provide localized and Unicode versions
+   *     of this string.  Applications should use the format-specific
+   *     interface to access them.
+   *
+   *   num_fixed_sizes ::
+   *     The number of bitmap strikes in the face.  Even if the face is
+   *     scalable, there might still be bitmap strikes, which are called
+   *     'sbits' in that case.
+   *
+   *   available_sizes ::
+   *     An array of @FT_Bitmap_Size for all bitmap strikes in the face.  It
+   *     is set to `NULL` if there is no bitmap strike.
+   *
+   *     Note that FreeType tries to sanitize the strike data since they are
+   *     sometimes sloppy or incorrect, but this can easily fail.
+   *
+   *   num_charmaps ::
+   *     The number of charmaps in the face.
+   *
+   *   charmaps ::
+   *     An array of the charmaps of the face.
+   *
+   *   generic ::
+   *     A field reserved for client uses.  See the @FT_Generic type
+   *     description.
+   *
+   *   bbox ::
+   *     The font bounding box.  Coordinates are expressed in font units (see
+   *     `units_per_EM`).  The box is large enough to contain any glyph from
+   *     the font.  Thus, `bbox.yMax` can be seen as the 'maximum ascender',
+   *     and `bbox.yMin` as the 'minimum descender'.  Only relevant for
+   *     scalable formats.
+   *
+   *     Note that the bounding box might be off by (at least) one pixel for
+   *     hinted fonts.  See @FT_Size_Metrics for further discussion.
+   *
+   *     Note that the bounding box does not vary in OpenType variable fonts
+   *     and should only be used in relation to the default instance.
+   *
+   *   units_per_EM ::
+   *     The number of font units per EM square for this face.  This is
+   *     typically 2048 for TrueType fonts, and 1000 for Type~1 fonts.  Only
+   *     relevant for scalable formats.
+   *
+   *   ascender ::
+   *     The typographic ascender of the face, expressed in font units.  For
+   *     font formats not having this information, it is set to `bbox.yMax`.
+   *     Only relevant for scalable formats.
+   *
+   *   descender ::
+   *     The typographic descender of the face, expressed in font units.  For
+   *     font formats not having this information, it is set to `bbox.yMin`.
+   *     Note that this field is negative for values below the baseline.
+   *     Only relevant for scalable formats.
+   *
+   *   height ::
+   *     This value is the vertical distance between two consecutive
+   *     baselines, expressed in font units.  It is always positive.  Only
+   *     relevant for scalable formats.
+   *
+   *     If you want the global glyph height, use `ascender - descender`.
+   *
+   *   max_advance_width ::
+   *     The maximum advance width, in font units, for all glyphs in this
+   *     face.  This can be used to make word wrapping computations faster.
+   *     Only relevant for scalable formats.
+   *
+   *   max_advance_height ::
+   *     The maximum advance height, in font units, for all glyphs in this
+   *     face.  This is only relevant for vertical layouts, and is set to
+   *     `height` for fonts that do not provide vertical metrics.  Only
+   *     relevant for scalable formats.
+   *
+   *   underline_position ::
+   *     The position, in font units, of the underline line for this face.
+   *     It is the center of the underlining stem.  Only relevant for
+   *     scalable formats.
+   *
+   *   underline_thickness ::
+   *     The thickness, in font units, of the underline for this face.  Only
+   *     relevant for scalable formats.
+   *
+   *   glyph ::
+   *     The face's associated glyph slot(s).
+   *
+   *   size ::
+   *     The current active size for this face.
+   *
+   *   charmap ::
+   *     The current active charmap for this face.
+   *
+   * @note:
+   *   Fields may be changed after a call to @FT_Attach_File or
+   *   @FT_Attach_Stream.
+   *
+   *   For an OpenType variation font, the values of the following fields can
+   *   change after a call to @FT_Set_Var_Design_Coordinates (and friends) if
+   *   the font contains an 'MVAR' table: `ascender`, `descender`, `height`,
+   *   `underline_position`, and `underline_thickness`.
+   *
+   *   Especially for TrueType fonts see also the documentation for
+   *   @FT_Size_Metrics.

+   *
+   * @description:
+   *   A list of bit flags used in the `face_flags` field of the @FT_FaceRec
+   *   structure.  They inform client applications of properties of the
+   *   corresponding face.
+   *
+   * @values:
+   *   FT_FACE_FLAG_SCALABLE ::
+   *     The face contains outline glyphs.  Note that a face can contain
+   *     bitmap strikes also, i.e., a face can have both this flag and
+   *     @FT_FACE_FLAG_FIXED_SIZES set.
+   *
+   *   FT_FACE_FLAG_FIXED_SIZES ::
+   *     The face contains bitmap strikes.  See also the `num_fixed_sizes`
+   *     and `available_sizes` fields of @FT_FaceRec.
+   *
+   *   FT_FACE_FLAG_FIXED_WIDTH ::
+   *     The face contains fixed-width characters (like Courier, Lucida,
+   *     MonoType, etc.).
+   *
+   *   FT_FACE_FLAG_SFNT ::
+   *     The face uses the SFNT storage scheme.  For now, this means TrueType
+   *     and OpenType.
+   *
+   *   FT_FACE_FLAG_HORIZONTAL ::
+   *     The face contains horizontal glyph metrics.  This should be set for
+   *     all common formats.
+   *
+   *   FT_FACE_FLAG_VERTICAL ::
+   *     The face contains vertical glyph metrics.  This is only available in
+   *     some formats, not all of them.
+   *
+   *   FT_FACE_FLAG_KERNING ::
+   *     The face contains kerning information.  If set, the kerning distance
+   *     can be retrieved using the function @FT_Get_Kerning.  Otherwise the
+   *     function always return the vector (0,0).  Note that FreeType doesn't
+   *     handle kerning data from the SFNT 'GPOS' table (as present in many
+   *     OpenType fonts).
+   *
+   *   FT_FACE_FLAG_FAST_GLYPHS ::
+   *     THIS FLAG IS DEPRECATED.  DO NOT USE OR TEST IT.
+   *
+   *   FT_FACE_FLAG_MULTIPLE_MASTERS ::
+   *     The face contains multiple masters and is capable of interpolating
+   *     between them.  Supported formats are Adobe MM, TrueType GX, and
+   *     OpenType variation fonts.
+   *
+   *     See section @multiple_masters for API details.
+   *
+   *   FT_FACE_FLAG_GLYPH_NAMES ::
+   *     The face contains glyph names, which can be retrieved using
+   *     @FT_Get_Glyph_Name.  Note that some TrueType fonts contain broken
+   *     glyph name tables.  Use the function @FT_Has_PS_Glyph_Names when
+   *     needed.
+   *
+   *   FT_FACE_FLAG_EXTERNAL_STREAM ::
+   *     Used internally by FreeType to indicate that a face's stream was
+   *     provided by the client application and should not be destroyed when
+   *     @FT_Done_Face is called.  Don't read or test this flag.
+   *
+   *   FT_FACE_FLAG_HINTER ::
+   *     The font driver has a hinting machine of its own.  For example, with
+   *     TrueType fonts, it makes sense to use data from the SFNT 'gasp'
+   *     table only if the native TrueType hinting engine (with the bytecode
+   *     interpreter) is available and active.
+   *
+   *   FT_FACE_FLAG_CID_KEYED ::
+   *     The face is CID-keyed.  In that case, the face is not accessed by
+   *     glyph indices but by CID values.  For subsetted CID-keyed fonts this
+   *     has the consequence that not all index values are a valid argument
+   *     to @FT_Load_Glyph.  Only the CID values for which corresponding
+   *     glyphs in the subsetted font exist make `FT_Load_Glyph` return
+   *     successfully; in all other cases you get an
+   *     `FT_Err_Invalid_Argument` error.
+   *
+   *     Note that CID-keyed fonts that are in an SFNT wrapper (this is, all
+   *     OpenType/CFF fonts) don't have this flag set since the glyphs are
+   *     accessed in the normal way (using contiguous indices); the
+   *     'CID-ness' isn't visible to the application.
+   *
+   *   FT_FACE_FLAG_TRICKY ::
+   *     The face is 'tricky', this is, it always needs the font format's
+   *     native hinting engine to get a reasonable result.  A typical example
+   *     is the old Chinese font `mingli.ttf` (but not `mingliu.ttc`) that
+   *     uses TrueType bytecode instructions to move and scale all of its
+   *     subglyphs.
+   *
+   *     It is not possible to auto-hint such fonts using
+   *     @FT_LOAD_FORCE_AUTOHINT; it will also ignore @FT_LOAD_NO_HINTING.
+   *     You have to set both @FT_LOAD_NO_HINTING and @FT_LOAD_NO_AUTOHINT to

+   *   FT_FACE_FLAG_COLOR ::
+   *     [Since 2.5.1] The face has color glyph tables.  See @FT_LOAD_COLOR
+   *     for more information.
+   *
+   *   FT_FACE_FLAG_VARIATION ::
+   *     [Since 2.9] Set if the current face (or named instance) has been
+   *     altered with @FT_Set_MM_Design_Coordinates,
+   *     @FT_Set_Var_Design_Coordinates, or @FT_Set_Var_Blend_Coordinates.

+   * @struct:
+   *   FT_Size_Metrics
+   *
+   * @description:
+   *   The size metrics structure gives the metrics of a size object.
+   *
+   * @fields:
+   *   x_ppem ::
+   *     The width of the scaled EM square in pixels, hence the term 'ppem'
+   *     (pixels per EM).  It is also referred to as 'nominal width'.
+   *
+   *   y_ppem ::
+   *     The height of the scaled EM square in pixels, hence the term 'ppem'
+   *     (pixels per EM).  It is also referred to as 'nominal height'.
+   *
+   *   x_scale ::
+   *     A 16.16 fractional scaling value to convert horizontal metrics from
+   *     font units to 26.6 fractional pixels.  Only relevant for scalable
+   *     font formats.
+   *
+   *   y_scale ::
+   *     A 16.16 fractional scaling value to convert vertical metrics from
+   *     font units to 26.6 fractional pixels.  Only relevant for scalable
+   *     font formats.
+   *
+   *   ascender ::
+   *     The ascender in 26.6 fractional pixels, rounded up to an integer
+   *     value.  See @FT_FaceRec for the details.
+   *
+   *   descender ::
+   *     The descender in 26.6 fractional pixels, rounded down to an integer
+   *     value.  See @FT_FaceRec for the details.
+   *
+   *   height ::
+   *     The height in 26.6 fractional pixels, rounded to an integer value.
+   *     See @FT_FaceRec for the details.
+   *
+   *   max_advance ::
+   *     The maximum advance width in 26.6 fractional pixels, rounded to an
+   *     integer value.  See @FT_FaceRec for the details.
+   *
+   * @note:
+   *   The scaling values, if relevant, are determined first during a size
+   *   changing operation.  The remaining fields are then set by the driver.
+   *   For scalable formats, they are usually set to scaled values of the
+   *   corresponding fields in @FT_FaceRec.  Some values like ascender or
+   *   descender are rounded for historical reasons; more precise values (for
+   *   outline fonts) can be derived by scaling the corresponding @FT_FaceRec
+   *   values manually, with code similar to the following.
+   *
+   *   ```
+   *     scaled_ascender = FT_MulFix( face->ascender,
+   *                                  size_metrics->y_scale );
+   *   ```
+   *
+   *   Note that due to glyph hinting and the selected rendering mode these
+   *   values are usually not exact; consequently, they must be treated as
+   *   unreliable with an error margin of at least one pixel!
+   *
+   *   Indeed, the only way to get the exact metrics is to render _all_
+   *   glyphs.  As this would be a definite performance hit, it is up to
+   *   client applications to perform such computations.
+   *
+   *   The `FT_Size_Metrics` structure is valid for bitmap fonts also.
+   *
+   *
+   *   **TrueType fonts with native bytecode hinting**
+   *
+   *   All applications that handle TrueType fonts with native hinting must
+   *   be aware that TTFs expect different rounding of vertical font
+   *   dimensions.  The application has to cater for this, especially if it
+   *   wants to rely on a TTF's vertical data (for example, to properly align
+   *   box characters vertically).
+   *
+   *   Only the application knows _in advance_ that it is going to use native
+   *   hinting for TTFs!  FreeType, on the other hand, selects the hinting
+   *   mode not at the time of creating an @FT_Size object but much later,
+   *   namely while calling @FT_Load_Glyph.
+   *
+   *   Here is some pseudo code that illustrates a possible solution.
+   *
+   *   ```
+   *     font_format = FT_Get_Font_Format( face );
+   *
+   *     if ( !strcmp( font_format, "TrueType" ) &&
+   *          do_native_bytecode_hinting         )
+   *     {
+   *       ascender  = ROUND( FT_MulFix( face->ascender,
+   *                                     size_metrics->y_scale ) );
+   *       descender = ROUND( FT_MulFix( face->descender,
+   *                                     size_metrics->y_scale ) );
+   *     }
+   *     else
+   *     {
+   *       ascender  = size_metrics->ascender;
+   *       descender = size_metrics->descender;
+   *     }
+   *
+   *     height      = size_metrics->height;
+   *     max_advance = size_metrics->max_advance;

+   * @struct:
+   *   FT_GlyphSlotRec
+   *
+   * @description:
+   *   FreeType root glyph slot class structure.  A glyph slot is a container
+   *   where individual glyphs can be loaded, be they in outline or bitmap
+   *   format.
+   *
+   * @fields:
+   *   library ::
+   *     A handle to the FreeType library instance this slot belongs to.
+   *
+   *   face ::
+   *     A handle to the parent face object.
+   *
+   *   next ::
+   *     In some cases (like some font tools), several glyph slots per face
+   *     object can be a good thing.  As this is rare, the glyph slots are
+   *     listed through a direct, single-linked list using its `next` field.
+   *
+   *   glyph_index ::
+   *     [Since 2.10] The glyph index passed as an argument to @FT_Load_Glyph
+   *     while initializing the glyph slot.
+   *
+   *   generic ::
+   *     A typeless pointer unused by the FreeType library or any of its
+   *     drivers.  It can be used by client applications to link their own
+   *     data to each glyph slot object.
+   *
+   *   metrics ::
+   *     The metrics of the last loaded glyph in the slot.  The returned
+   *     values depend on the last load flags (see the @FT_Load_Glyph API
+   *     function) and can be expressed either in 26.6 fractional pixels or
+   *     font units.
+   *
+   *     Note that even when the glyph image is transformed, the metrics are
+   *     not.
+   *
+   *   linearHoriAdvance ::
+   *     The advance width of the unhinted glyph.  Its value is expressed in
+   *     16.16 fractional pixels, unless @FT_LOAD_LINEAR_DESIGN is set when
+   *     loading the glyph.  This field can be important to perform correct
+   *     WYSIWYG layout.  Only relevant for outline glyphs.
+   *
+   *   linearVertAdvance ::
+   *     The advance height of the unhinted glyph.  Its value is expressed in
+   *     16.16 fractional pixels, unless @FT_LOAD_LINEAR_DESIGN is set when
+   *     loading the glyph.  This field can be important to perform correct
+   *     WYSIWYG layout.  Only relevant for outline glyphs.
+   *
+   *   advance ::
+   *     This shorthand is, depending on @FT_LOAD_IGNORE_TRANSFORM, the
+   *     transformed (hinted) advance width for the glyph, in 26.6 fractional
+   *     pixel format.  As specified with @FT_LOAD_VERTICAL_LAYOUT, it uses
+   *     either the `horiAdvance` or the `vertAdvance` value of `metrics`
+   *     field.
+   *
+   *   format ::
+   *     This field indicates the format of the image contained in the glyph
+   *     slot.  Typically @FT_GLYPH_FORMAT_BITMAP, @FT_GLYPH_FORMAT_OUTLINE,
+   *     or @FT_GLYPH_FORMAT_COMPOSITE, but other values are possible.
+   *
+   *   bitmap ::
+   *     This field is used as a bitmap descriptor.  Note that the address
+   *     and content of the bitmap buffer can change between calls of
+   *     @FT_Load_Glyph and a few other functions.
+   *
+   *   bitmap_left ::
+   *     The bitmap's left bearing expressed in integer pixels.
+   *
+   *   bitmap_top ::
+   *     The bitmap's top bearing expressed in integer pixels.  This is the
+   *     distance from the baseline to the top-most glyph scanline, upwards
+   *     y~coordinates being **positive**.
+   *
+   *   outline ::
+   *     The outline descriptor for the current glyph image if its format is
+   *     @FT_GLYPH_FORMAT_OUTLINE.  Once a glyph is loaded, `outline` can be
+   *     transformed, distorted, emboldened, etc.  However, it must not be
+   *     freed.
+   *
+   *     [Since 2.10.1] If @FT_LOAD_NO_SCALE is set, outline coordinates of
+   *     OpenType variation fonts for a selected instance are internally
+   *     handled as 26.6 fractional font units but returned as (rounded)
+   *     integers, as expected.  To get unrounded font units, don't use
+   *     @FT_LOAD_NO_SCALE but load the glyph with @FT_LOAD_NO_HINTING and
+   *     scale it, using the font's `units_per_EM` value as the ppem.
+   *
+   *   num_subglyphs ::
+   *     The number of subglyphs in a composite glyph.  This field is only
+   *     valid for the composite glyph format that should normally only be
+   *     loaded with the @FT_LOAD_NO_RECURSE flag.
+   *
+   *   subglyphs ::
+   *     An array of subglyph descriptors for composite glyphs.  There are
+   *     `num_subglyphs` elements in there.  Currently internal to FreeType.
+   *
+   *   control_data ::
+   *     Certain font drivers can also return the control data for a given
+   *     glyph image (e.g.  TrueType bytecode, Type~1 charstrings, etc.).
+   *     This field is a pointer to such data; it is currently internal to
+   *     FreeType.
+   *
+   *   control_len ::
+   *     This is the length in bytes of the control data.  Currently internal
+   *     to FreeType.
+   *
+   *   other ::
+   *     Reserved.
+   *
+   *   lsb_delta ::
+   *     The difference between hinted and unhinted left side bearing while
+   *     auto-hinting is active.  Zero otherwise.
+   *
+   *   rsb_delta ::
+   *     The difference between hinted and unhinted right side bearing while
+   *     auto-hinting is active.  Zero otherwise.
+   *
+   * @note:
+   *   If @FT_Load_Glyph is called with default flags (see @FT_LOAD_DEFAULT)
+   *   the glyph image is loaded in the glyph slot in its native format
+   *   (e.g., an outline glyph for TrueType and Type~1 formats).  [Since 2.9]
+   *   The prospective bitmap metrics are calculated according to
+   *   @FT_LOAD_TARGET_XXX and other flags even for the outline glyph, even
+   *   if @FT_LOAD_RENDER is not set.
+   *
+   *   This image can later be converted into a bitmap by calling
+   *   @FT_Render_Glyph.  This function searches the current renderer for the
+   *   native image's format, then invokes it.
+   *
+   *   The renderer is in charge of transforming the native image through the
+   *   slot's face transformation fields, then converting it into a bitmap
+   *   that is returned in `slot->bitmap`.
+   *
+   *   Note that `slot->bitmap_left` and `slot->bitmap_top` are also used to
+   *   specify the position of the bitmap relative to the current pen
+   *   position (e.g., coordinates (0,0) on the baseline).  Of course,
+   *   `slot->format` is also changed to @FT_GLYPH_FORMAT_BITMAP.
+   *
+   *   Here is a small pseudo code fragment that shows how to use `lsb_delta`
+   *   and `rsb_delta` to do fractional positioning of glyphs:
+   *
+   *   ```
+   *     FT_GlyphSlot  slot     = face->glyph;
+   *     FT_Pos        origin_x = 0;
+   *
+   *
+   *     for all glyphs do
+   *       <load glyph with `FT_Load_Glyph'>
+   *
+   *       FT_Outline_Translate( slot->outline, origin_x & 63, 0 );
+   *
+   *       <save glyph image, or render glyph, or ...>
+   *
+   *       <compute kern between current and next glyph
+   *        and add it to `origin_x'>
+   *
+   *       origin_x += slot->advance.x;
+   *       origin_x += slot->lsb_delta - slot->rsb_delta;
+   *     endfor
+   *   ```
+   *
+   *   Here is another small pseudo code fragment that shows how to use
+   *   `lsb_delta` and `rsb_delta` to improve integer positioning of glyphs:
+   *
+   *   ```
+   *     FT_GlyphSlot  slot           = face->glyph;
+   *     FT_Pos        origin_x       = 0;
+   *     FT_Pos        prev_rsb_delta = 0;
+   *
+   *
+   *     for all glyphs do
+   *       <compute kern between current and previous glyph
+   *        and add it to `origin_x'>
+   *
+   *       <load glyph with `FT_Load_Glyph'>
+   *
+   *       if ( prev_rsb_delta - slot->lsb_delta >  32 )
+   *         origin_x -= 64;
+   *       else if ( prev_rsb_delta - slot->lsb_delta < -31 )
+   *         origin_x += 64;
+   *
+   *       prev_rsb_delta = slot->rsb_delta;
+   *
+   *       <save glyph image, or render glyph, or ...>
+   *
+   *       origin_x += slot->advance.x;
+   *     endfor
+   *   ```
+   *
+   *   If you use strong auto-hinting, you **must** apply these delta values!
+   *   Otherwise you will experience far too large inter-glyph spacing at
+   *   small rendering sizes in most cases.  Note that it doesn't harm to use
+   *   the above code for other hinting modes also, since the delta values
+   *   are zero then.

+   * @function:
+   *   FT_Open_Face
+   *
+   * @description:
+   *   Create a face object from a given resource described by @FT_Open_Args.
+   *
+   * @inout:
+   *   library ::
+   *     A handle to the library resource.
+   *
+   * @input:
+   *   args ::
+   *     A pointer to an `FT_Open_Args` structure that must be filled by the
+   *     caller.
+   *
+   *   face_index ::
+   *     This field holds two different values.  Bits 0-15 are the index of
+   *     the face in the font file (starting with value~0).  Set it to~0 if
+   *     there is only one face in the font file.
+   *
+   *     [Since 2.6.1] Bits 16-30 are relevant to GX and OpenType variation
+   *     fonts only, specifying the named instance index for the current face
+   *     index (starting with value~1; value~0 makes FreeType ignore named
+   *     instances).  For non-variation fonts, bits 16-30 are ignored.
+   *     Assuming that you want to access the third named instance in face~4,
+   *     `face_index` should be set to 0x00030004.  If you want to access
+   *     face~4 without variation handling, simply set `face_index` to
+   *     value~4.
+   *
+   *     `FT_Open_Face` and its siblings can be used to quickly check whether
+   *     the font format of a given font resource is supported by FreeType.
+   *     In general, if the `face_index` argument is negative, the function's
+   *     return value is~0 if the font format is recognized, or non-zero
+   *     otherwise.  The function allocates a more or less empty face handle
+   *     in `*aface` (if `aface` isn't `NULL`); the only two useful fields in
+   *     this special case are `face->num_faces` and `face->style_flags`.
+   *     For any negative value of `face_index`, `face->num_faces` gives the
+   *     number of faces within the font file.  For the negative value
+   *     '-(N+1)' (with 'N' a non-negative 16-bit value), bits 16-30 in
+   *     `face->style_flags` give the number of named instances in face 'N'
+   *     if we have a variation font (or zero otherwise).  After examination,
+   *     the returned @FT_Face structure should be deallocated with a call to
+   *     @FT_Done_Face.
+   *
+   * @output:
+   *   aface ::
+   *     A handle to a new face object.  If `face_index` is greater than or
+   *     equal to zero, it must be non-`NULL`.
+   *
+   * @return:
+   *   FreeType error code.  0~means success.
+   *
+   * @note:
+   *   Unlike FreeType 1.x, this function automatically creates a glyph slot
+   *   for the face object that can be accessed directly through
+   *   `face->glyph`.
+   *
+   *   Each new face object created with this function also owns a default
+   *   @FT_Size object, accessible as `face->size`.
+   *
+   *   One @FT_Library instance can have multiple face objects, this is,
+   *   @FT_Open_Face and its siblings can be called multiple times using the
+   *   same `library` argument.
+   *
+   *   See the discussion of reference counters in the description of
+   *   @FT_Reference_Face.
+   *
+   * @example:
+   *   To loop over all faces, use code similar to the following snippet
+   *   (omitting the error handling).
+   *
+   *   ```
+   *     ...
+   *     FT_Face  face;
+   *     FT_Long  i, num_faces;
+   *
+   *
+   *     error = FT_Open_Face( library, args, -1, &face );
+   *     if ( error ) { ... }
+   *
+   *     num_faces = face->num_faces;
+   *     FT_Done_Face( face );
+   *
+   *     for ( i = 0; i < num_faces; i++ )
+   *     {
+   *       ...
+   *       error = FT_Open_Face( library, args, i, &face );
+   *       ...
+   *       FT_Done_Face( face );
+   *       ...
+   *     }
+   *   ```
+   *
+   *   To loop over all valid values for `face_index`, use something similar
+   *   to the following snippet, again without error handling.  The code
+   *   accesses all faces immediately (thus only a single call of
+   *   `FT_Open_Face` within the do-loop), with and without named instances.
+   *
+   *   ```
+   *     ...
+   *     FT_Face  face;
+   *
+   *     FT_Long  num_faces     = 0;
+   *     FT_Long  num_instances = 0;
+   *
+   *     FT_Long  face_idx     = 0;
+   *     FT_Long  instance_idx = 0;
+   *
+   *
+   *     do
+   *     {
+   *       FT_Long  id = ( instance_idx << 16 ) + face_idx;
+   *
+   *
+   *       error = FT_Open_Face( library, args, id, &face );
+   *       if ( error ) { ... }
+   *
+   *       num_faces     = face->num_faces;
+   *       num_instances = face->style_flags >> 16;
+   *
+   *       ...
+   *
+   *       FT_Done_Face( face );
+   *
+   *       if ( instance_idx < num_instances )
+   *         instance_idx++;
+   *       else
+   *       {
+   *         face_idx++;
+   *         instance_idx = 0;
+   *       }
+   *

+   * @enum:
+   *   FT_Size_Request_Type
+   *
+   * @description:
+   *   An enumeration type that lists the supported size request types, i.e.,
+   *   what input size (in font units) maps to the requested output size (in
+   *   pixels, as computed from the arguments of @FT_Size_Request).
+   *
+   * @values:
+   *   FT_SIZE_REQUEST_TYPE_NOMINAL ::
+   *     The nominal size.  The `units_per_EM` field of @FT_FaceRec is used
+   *     to determine both scaling values.
+   *
+   *     This is the standard scaling found in most applications.  In
+   *     particular, use this size request type for TrueType fonts if they
+   *     provide optical scaling or something similar.  Note, however, that
+   *     `units_per_EM` is a rather abstract value which bears no relation to
+   *     the actual size of the glyphs in a font.
+   *
+   *   FT_SIZE_REQUEST_TYPE_REAL_DIM ::
+   *     The real dimension.  The sum of the `ascender` and (minus of) the
+   *     `descender` fields of @FT_FaceRec is used to determine both scaling
+   *     values.
+   *
+   *   FT_SIZE_REQUEST_TYPE_BBOX ::
+   *     The font bounding box.  The width and height of the `bbox` field of
+   *     @FT_FaceRec are used to determine the horizontal and vertical
+   *     scaling value, respectively.
+   *
+   *   FT_SIZE_REQUEST_TYPE_CELL ::
+   *     The `max_advance_width` field of @FT_FaceRec is used to determine
+   *     the horizontal scaling value; the vertical scaling value is
+   *     determined the same way as @FT_SIZE_REQUEST_TYPE_REAL_DIM does.
+   *     Finally, both scaling values are set to the smaller one.  This type
+   *     is useful if you want to specify the font size for, say, a window of
+   *     a given dimension and 80x24 cells.
+   *
+   *   FT_SIZE_REQUEST_TYPE_SCALES ::
+   *     Specify the scaling values directly.
+   *
+   * @note:
+   *   The above descriptions only apply to scalable formats.  For bitmap
+   *   formats, the behaviour is up to the driver.
+   *
+   *   See the note section of @FT_Size_Metrics if you wonder how size
+   *   requesting relates to scaling values.

+   *   FT_Render_Glyph
+   *
+   * @description:
+   *   Convert a given glyph image to a bitmap.  It does so by inspecting the
+   *   glyph image format, finding the relevant renderer, and invoking it.
+   *
+   * @inout:
+   *   slot ::
+   *     A handle to the glyph slot containing the image to convert.
+   *
+   * @input:
+   *   render_mode ::
+   *     The render mode used to render the glyph image into a bitmap.  See
+   *     @FT_Render_Mode for a list of possible values.
+   *
+   *     If @FT_RENDER_MODE_NORMAL is used, a previous call of @FT_Load_Glyph
+   *     with flag @FT_LOAD_COLOR makes FT_Render_Glyph provide a default
+   *     blending of colored glyph layers associated with the current glyph
+   *     slot (provided the font contains such layers) instead of rendering
+   *     the glyph slot's outline.  This is an experimental feature; see
+   *     @FT_LOAD_COLOR for more information.
+   *
+   * @return:
+   *   FreeType error code.  0~means success.
+   *
+   * @note:
+   *   To get meaningful results, font scaling values must be set with
+   *   functions like @FT_Set_Char_Size before calling `FT_Render_Glyph`.
+   *
+   *   When FreeType outputs a bitmap of a glyph, it really outputs an alpha
+   *   coverage map.  If a pixel is completely covered by a filled-in
+   *   outline, the bitmap contains 0xFF at that pixel, meaning that
+   *   0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100%
+   *   black (or 0% bright).  If a pixel is only 50% covered (value 0x80),
+   *   the pixel is made 50% black (50% bright or a middle shade of grey).
+   *   0% covered means 0% black (100% bright or white).
+   *
+   *   On high-DPI screens like on smartphones and tablets, the pixels are so
+   *   small that their chance of being completely covered and therefore
+   *   completely black are fairly good.  On the low-DPI screens, however,
+   *   the situation is different.  The pixels are too large for most of the
+   *   details of a glyph and shades of gray are the norm rather than the
+   *   exception.
+   *
+   *   This is relevant because all our screens have a second problem: they
+   *   are not linear.  1~+~1 is not~2.  Twice the value does not result in
+   *   twice the brightness.  When a pixel is only 50% covered, the coverage
+   *   map says 50% black, and this translates to a pixel value of 128 when
+   *   you use 8~bits per channel (0-255).  However, this does not translate
+   *   to 50% brightness for that pixel on our sRGB and gamma~2.2 screens.
+   *   Due to their non-linearity, they dwell longer in the darks and only a
+   *   pixel value of about 186 results in 50% brightness -- 128 ends up too
+   *   dark on both bright and dark backgrounds.  The net result is that dark
+   *   text looks burnt-out, pixely and blotchy on bright background, bright
+   *   text too frail on dark backgrounds, and colored text on colored
+   *   background (for example, red on green) seems to have dark halos or
+   *   'dirt' around it.  The situation is especially ugly for diagonal stems
+   *   like in 'w' glyph shapes where the quality of FreeType's anti-aliasing
+   *   depends on the correct display of grays.  On high-DPI screens where
+   *   smaller, fully black pixels reign supreme, this doesn't matter, but on
+   *   our low-DPI screens with all the gray shades, it does.  0% and 100%
+   *   brightness are the same things in linear and non-linear space, just
+   *   all the shades in-between aren't.
+   *
+   *   The blending function for placing text over a background is
+   *
+   *   ```
+   *     dst = alpha * src + (1 - alpha) * dst    ,
+   *   ```
+   *
+   *   which is known as the OVER operator.
+   *
+   *   To correctly composite an antialiased pixel of a glyph onto a surface,
+   *
+   *   1. take the foreground and background colors (e.g., in sRGB space)
+   *      and apply gamma to get them in a linear space,
+   *
+   *   2. use OVER to blend the two linear colors using the glyph pixel
+   *      as the alpha value (remember, the glyph bitmap is an alpha coverage
+   *      bitmap), and
+   *
+   *   3. apply inverse gamma to the blended pixel and write it back to
+   *      the image.
+   *
+   *   Internal testing at Adobe found that a target inverse gamma of~1.8 for
+   *   step~3 gives good results across a wide range of displays with an sRGB
+   *   gamma curve or a similar one.
+   *
+   *   This process can cost performance.  There is an approximation that
+   *   does not need to know about the background color; see
+   *   https://bel.fi/alankila/lcd/ and
+   *   https://bel.fi/alankila/lcd/alpcor.html for details.

+   *   This is an interface to the 'COLR' table in OpenType fonts to
+   *   iteratively retrieve the colored glyph layers associated with the

+   *
+   *     https://docs.microsoft.com/en-us/typography/opentype/spec/colr
+   *
+   *   The glyph layer data for a given glyph index, if present, provides an
+   *   alternative, multi-color glyph representation: Instead of rendering
+   *   the outline or bitmap with the given glyph index, glyphs with the
+   *   indices and colors returned by this function are rendered layer by
+   *   layer.
+   *
+   *   The returned elements are ordered in the z~direction from bottom to
+   *   top; the 'n'th element should be rendered with the associated palette
+   *   color and blended on top of the already rendered layers (elements 0,
+   *   1, ..., n-1).
+   *
+   * @input:
+   *   face ::
+   *     A handle to the parent face object.
+   *
+   *   base_glyph ::
+   *     The glyph index the colored glyph layers are associated with.
+   *
+   * @inout:
+   *   iterator ::
+   *     An @FT_LayerIterator object.  For the first call you should set
+   *     `iterator->p` to `NULL`.  For all following calls, simply use the
+   *     same object again.
+   *
+   * @output:
+   *   aglyph_index ::
+   *     The glyph index of the current layer.
+   *
+   *   acolor_index ::
+   *     The color index into the font face's color palette of the current
+   *     layer.  The value 0xFFFF is special; it doesn't reference a palette
+   *     entry but indicates that the text foreground color should be used
+   *     instead (to be set up by the application outside of FreeType).
+   *
+   *     The color palette can be retrieved with @FT_Palette_Select.
+   *
+   * @return:
+   *   Value~1 if everything is OK.  If there are no more layers (or if there
+   *   are no layers at all), value~0 gets returned.  In case of an error,
+   *   value~0 is returned also.
+   *
+   * @note:
+   *   This function is necessary if you want to handle glyph layers by
+   *   yourself.  In particular, functions that operate with @FT_GlyphRec
+   *   objects (like @FT_Get_Glyph or @FT_Glyph_To_Bitmap) don't have access
+   *   to this information.
+   *
+   *   Note that @FT_Render_Glyph is able to handle colored glyph layers
+   *   automatically if the @FT_LOAD_COLOR flag is passed to a previous call
+   *   to @FT_Load_Glyph.  [This is an experimental feature.]
+   *
+   * @example:
+   *   ```
+   *     FT_Color*         palette;
+   *     FT_LayerIterator  iterator;

+   *
+   *     iterator.p  = NULL;
+   *     have_layers = FT_Get_Color_Glyph_Layer( face,

+   * @description:
+   *   Many characters, especially for CJK scripts, have variant forms.  They
+   *   are a sort of grey area somewhere between being totally irrelevant and
+   *   semantically distinct; for this reason, the Unicode consortium decided
+   *   to introduce Variation Sequences (VS), consisting of a Unicode base
+   *   character and a variation selector instead of further extending the
+   *   already huge number of characters.
+   *
+   *   Unicode maintains two different sets, namely 'Standardized Variation
+   *   Sequences' and registered 'Ideographic Variation Sequences' (IVS),
+   *   collected in the 'Ideographic Variation Database' (IVD).
+   *
+   *     https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt
+   *     https://unicode.org/reports/tr37/ https://unicode.org/ivd/
+   *
+   *   To date (January 2017), the character with the most ideographic
+   *   variations is U+9089, having 32 such IVS.
+   *
+   *   Three Mongolian Variation Selectors have the values U+180B-U+180D; 256
+   *   generic Variation Selectors are encoded in the ranges U+FE00-U+FE0F
+   *   and U+E0100-U+E01EF.  IVS currently use Variation Selectors from the
+   *   range U+E0100-U+E01EF only.
+   *
+   *   A VS consists of the base character value followed by a single
+   *   Variation Selector.  For example, to get the first variation of
+   *   U+9089, you have to write the character sequence `U+9089 U+E0100`.
+   *
+   *   Adobe and MS decided to support both standardized and ideographic VS
+   *   with a new cmap subtable (format~14).  It is an odd subtable because
+   *   it is not a mapping of input code points to glyphs, but contains lists
+   *   of all variations supported by the font.
+   *
+   *   A variation may be either 'default' or 'non-default' for a given font.
+   *   A default variation is the one you will get for that code point if you
+   *   look it up in the standard Unicode cmap.  A non-default variation is a
+   *   different glyph.

+   *
+   * @title:
+   *   Error Enumerations
+   *
+   * @abstract:
+   *   How to handle errors and error strings.
+   *
+   * @description:
+   *   The header file `fterrors.h` (which is automatically included by
+   *   `freetype.h` defines the handling of FreeType's enumeration
+   *   constants.  It can also be used to generate error message strings
+   *   with a small macro trick explained below.
+   *
+   *   **Error Formats**
+   *
+   *   The configuration macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` can be
+   *   defined in `ftoption.h` in order to make the higher byte indicate the
+   *   module where the error has happened (this is not compatible with
+   *   standard builds of FreeType~2, however).  See the file `ftmoderr.h`
+   *   for more details.
+   *
+   *   **Error Message Strings**
+   *
+   *   Error definitions are set up with special macros that allow client
+   *   applications to build a table of error message strings.  The strings
+   *   are not included in a normal build of FreeType~2 to save space (most
+   *   client applications do not use them).
+   *
+   *   To do so, you have to define the following macros before including
+   *   this file.
+   *
+   *   ```
+   *     FT_ERROR_START_LIST
+   *   ```
+   *
+   *   This macro is called before anything else to define the start of the
+   *   error list.  It is followed by several `FT_ERROR_DEF` calls.
+   *
+   *   ```
+   *     FT_ERROR_DEF( e, v, s )
+   *   ```
+   *
+   *   This macro is called to define one single error.  'e' is the error
+   *   code identifier (e.g., `Invalid_Argument`), 'v' is the error's
+   *   numerical value, and 's' is the corresponding error string.
+   *
+   *   ```
+   *     FT_ERROR_END_LIST
+   *   ```
+   *
+   *   This macro ends the list.
+   *
+   *   Additionally, you have to undefine `FTERRORS_H_` before #including
+   *   this file.
+   *
+   *   Here is a simple example.
+   *
+   *   ```
+   *     #undef FTERRORS_H_
+   *     #define FT_ERRORDEF( e, v, s )  { e, s },
+   *     #define FT_ERROR_START_LIST     {
+   *     #define FT_ERROR_END_LIST       { 0, NULL } };
+   *
+   *     const struct
+   *     {
+   *       int          err_code;
+   *       const char*  err_msg;
+   *     } ft_errors[] =
+   *
+   *     #include <freetype/fterrors.h>
+   *   ```
+   *
+   *   An alternative to using an array is a switch statement.
+   *
+   *   ```
+   *     #undef FTERRORS_H_
+   *     #define FT_ERROR_START_LIST     switch ( error_code ) {
+   *     #define FT_ERRORDEF( e, v, s )    case v: return s;
+   *     #define FT_ERROR_END_LIST       }
+   *   ```
+   *
+   *   If you use `FT_CONFIG_OPTION_USE_MODULE_ERRORS`, `error_code` should
+   *   be replaced with `FT_ERROR_BASE(error_code)` in the last example.

+   *   An enumeration type used to describe the format of pixels in a given
+   *   bitmap.  Note that additional formats may be added in the future.
+   *
+   * @values:
+   *   FT_PIXEL_MODE_NONE ::
+   *     Value~0 is reserved.
+   *
+   *   FT_PIXEL_MODE_MONO ::
+   *     A monochrome bitmap, using 1~bit per pixel.  Note that pixels are
+   *     stored in most-significant order (MSB), which means that the
+   *     left-most pixel in a byte has value 128.
+   *
+   *   FT_PIXEL_MODE_GRAY ::
+   *     An 8-bit bitmap, generally used to represent anti-aliased glyph
+   *     images.  Each pixel is stored in one byte.  Note that the number of
+   *     'gray' levels is stored in the `num_grays` field of the @FT_Bitmap
+   *     structure (it generally is 256).
+   *
+   *   FT_PIXEL_MODE_GRAY2 ::
+   *     A 2-bit per pixel bitmap, used to represent embedded anti-aliased
+   *     bitmaps in font files according to the OpenType specification.  We
+   *     haven't found a single font using this format, however.
+   *
+   *   FT_PIXEL_MODE_GRAY4 ::
+   *     A 4-bit per pixel bitmap, representing embedded anti-aliased bitmaps
+   *     in font files according to the OpenType specification.  We haven't
+   *     found a single font using this format, however.
+   *
+   *   FT_PIXEL_MODE_LCD ::
+   *     An 8-bit bitmap, representing RGB or BGR decimated glyph images used
+   *     for display on LCD displays; the bitmap is three times wider than
+   *     the original glyph image.  See also @FT_RENDER_MODE_LCD.
+   *
+   *   FT_PIXEL_MODE_LCD_V ::
+   *     An 8-bit bitmap, representing RGB or BGR decimated glyph images used
+   *     for display on rotated LCD displays; the bitmap is three times
+   *     taller than the original glyph image.  See also
+   *     @FT_RENDER_MODE_LCD_V.
+   *
+   *   FT_PIXEL_MODE_BGRA ::
+   *     [Since 2.5] An image with four 8-bit channels per pixel,
+   *     representing a color image (such as emoticons) with alpha channel.
+   *     For each pixel, the format is BGRA, which means, the blue channel
+   *     comes first in memory.  The color channels are pre-multiplied and in
+   *     the sRGB colorspace.  For example, full red at half-translucent
+   *     opacity will be represented as '00,00,80,80', not '00,00,FF,80'.
+   *     See also @FT_LOAD_COLOR.

+   *   A structure used to describe a bitmap or pixmap to the raster.  Note
+   *   that we now manage pixmaps of various depths through the `pixel_mode`
+   *   field.
+   *
+   * @fields:
+   *   rows ::
+   *     The number of bitmap rows.
+   *
+   *   width ::
+   *     The number of pixels in bitmap row.
+   *
+   *   pitch ::
+   *     The pitch's absolute value is the number of bytes taken by one
+   *     bitmap row, including padding.  However, the pitch is positive when
+   *     the bitmap has a 'down' flow, and negative when it has an 'up' flow.
+   *     In all cases, the pitch is an offset to add to a bitmap pointer in
+   *     order to go down one row.
+   *
+   *     Note that 'padding' means the alignment of a bitmap to a byte
+   *     border, and FreeType functions normally align to the smallest
+   *     possible integer value.
+   *
+   *     For the B/W rasterizer, `pitch` is always an even number.
+   *
+   *     To change the pitch of a bitmap (say, to make it a multiple of 4),
+   *     use @FT_Bitmap_Convert.  Alternatively, you might use callback
+   *     functions to directly render to the application's surface; see the
+   *     file `example2.cpp` in the tutorial for a demonstration.
+   *
+   *   buffer ::
+   *     A typeless pointer to the bitmap buffer.  This value should be
+   *     aligned on 32-bit boundaries in most cases.
+   *
+   *   num_grays ::
+   *     This field is only used with @FT_PIXEL_MODE_GRAY; it gives the
+   *     number of gray levels used in the bitmap.
+   *
+   *   pixel_mode ::
+   *     The pixel mode, i.e., how pixel bits are stored.  See @FT_Pixel_Mode
+   *     for possible values.
+   *
+   *   palette_mode ::

+   *
+   * @fields:
+   *   n_contours ::
+   *     The number of contours in the outline.
+   *
+   *   n_points ::
+   *     The number of points in the outline.
+   *
+   *   points ::
+   *     A pointer to an array of `n_points` @FT_Vector elements, giving the
+   *     outline's point coordinates.
+   *
+   *   tags ::
+   *     A pointer to an array of `n_points` chars, giving each outline
+   *     point's type.
+   *
+   *     If bit~0 is unset, the point is 'off' the curve, i.e., a Bezier
+   *     control point, while it is 'on' if set.
+   *
+   *     Bit~1 is meaningful for 'off' points only.  If set, it indicates a
+   *     third-order Bezier arc control point; and a second-order control
+   *     point if unset.
+   *
+   *     If bit~2 is set, bits 5-7 contain the drop-out mode (as defined in
+   *     the OpenType specification; the value is the same as the argument to
+   *     the 'SCANMODE' instruction).
+   *
+   *     Bits 3 and~4 are reserved for internal purposes.
+   *
+   *   contours ::
+   *     An array of `n_contours` shorts, giving the end point of each
+   *     contour within the outline.  For example, the first contour is
+   *     defined by the points '0' to `contours[0]`, the second one is
+   *     defined by the points `contours[0]+1` to `contours[1]`, etc.
+   *
+   *   flags ::
+   *     A set of bit flags used to characterize the outline and give hints
+   *     to the scan-converter and hinter on how to convert/grid-fit it.  See
+   *     @FT_OUTLINE_XXX.
+   *
+   * @note:
+   *   The B/W rasterizer only checks bit~2 in the `tags` array for the first
+   *   point of each contour.  The drop-out mode as given with
+   *   @FT_OUTLINE_IGNORE_DROPOUTS, @FT_OUTLINE_SMART_DROPOUTS, and
+   *   @FT_OUTLINE_INCLUDE_STUBS in `flags` is then overridden.

+   *   `flags` field.
+   *
+   * @values:
+   *   FT_OUTLINE_NONE ::
+   *     Value~0 is reserved.
+   *
+   *   FT_OUTLINE_OWNER ::
+   *     If set, this flag indicates that the outline's field arrays (i.e.,
+   *     `points`, `flags`, and `contours`) are 'owned' by the outline
+   *     object, and should thus be freed when it is destroyed.
+   *
+   *   FT_OUTLINE_EVEN_ODD_FILL ::
+   *     By default, outlines are filled using the non-zero winding rule.  If
+   *     set to 1, the outline will be filled using the even-odd fill rule
+   *     (only works with the smooth rasterizer).
+   *
+   *   FT_OUTLINE_REVERSE_FILL ::
+   *     By default, outside contours of an outline are oriented in
+   *     clock-wise direction, as defined in the TrueType specification.
+   *     This flag is set if the outline uses the opposite direction
+   *     (typically for Type~1 fonts).  This flag is ignored by the scan
+   *     converter.
+   *
+   *   FT_OUTLINE_IGNORE_DROPOUTS ::
+   *     By default, the scan converter will try to detect drop-outs in an
+   *     outline and correct the glyph bitmap to ensure consistent shape
+   *     continuity.  If set, this flag hints the scan-line converter to
+   *     ignore such cases.  See below for more information.
+   *
+   *   FT_OUTLINE_SMART_DROPOUTS ::
+   *     Select smart dropout control.  If unset, use simple dropout control.
+   *     Ignored if @FT_OUTLINE_IGNORE_DROPOUTS is set.  See below for more
+   *     information.
+   *
+   *   FT_OUTLINE_INCLUDE_STUBS ::
+   *     If set, turn pixels on for 'stubs', otherwise exclude them.  Ignored
+   *     if @FT_OUTLINE_IGNORE_DROPOUTS is set.  See below for more
+   *     information.
+   *
+   *   FT_OUTLINE_OVERLAP ::
+   *     This flag indicates that this outline contains overlapping contrours
+   *     and the anti-aliased renderer should perform oversampling to
+   *     mitigate possible artifacts.  This flag should _not_ be set for
+   *     well designed glyphs without overlaps because it quadruples the
+   *     rendering time.
+   *
+   *   FT_OUTLINE_HIGH_PRECISION ::
+   *     This flag indicates that the scan-line converter should try to
+   *     convert this outline to bitmaps with the highest possible quality.
+   *     It is typically set for small character sizes.  Note that this is
+   *     only a hint that might be completely ignored by a given
+   *     scan-converter.
+   *
+   *   FT_OUTLINE_SINGLE_PASS ::
+   *     This flag is set to force a given scan-converter to only use a
+   *     single pass over the outline to render a bitmap glyph image.
+   *     Normally, it is set for very large character sizes.  It is only a
+   *     hint that might be completely ignored by a given scan-converter.

+   * @note:
+   *   The flags @FT_OUTLINE_IGNORE_DROPOUTS, @FT_OUTLINE_SMART_DROPOUTS, and
+   *   @FT_OUTLINE_INCLUDE_STUBS are ignored by the smooth rasterizer.
+   *
+   *   There exists a second mechanism to pass the drop-out mode to the B/W

+   *   does not support the direct mode.

+   *   The gray-level rasterizer always uses 256 gray levels.  If you want

-   *   LCD Filtering
+   *   Subpixel Rendering
    *
    * @abstract:
-   *   Reduce color fringes of subpixel-rendered bitmaps.
+   *   API to control subpixel rendering.
    *
    * @description:
-   *   Should you #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your
-   *   `ftoption.h', which enables patented ClearType-style rendering,
-   *   the LCD-optimized glyph bitmaps should be filtered to reduce color
-   *   fringes inherent to this technology.  The default FreeType LCD
-   *   rendering uses different technology, and API described below,
-   *   although available, does nothing.
+   *   FreeType provides two alternative subpixel rendering technologies. 
+   *   Should you define `FT_CONFIG_OPTION_SUBPIXEL_RENDERING` in your
+   *   `ftoption.h` file, this enables ClearType-style rendering.
+   *   Otherwise, Harmony LCD rendering is enabled.  These technologies are
+   *   controlled differently and API described below, although always
+   *   available, performs its function when appropriate method is enabled
+   *   and does nothing otherwise.
    *
    *   ClearType-style LCD rendering exploits the color-striped structure of
    *   LCD pixels, increasing the available resolution in the direction of
-   *   the stripe (usually horizontal RGB) by a factor of~3.  Since these
-   *   subpixels are color pixels, using them unfiltered creates severe
-   *   color fringes.  Use the @FT_Library_SetLcdFilter API to specify a
-   *   low-pass filter, which is then applied to subpixel-rendered bitmaps
-   *   generated through @FT_Render_Glyph.  The filter sacrifices some of
-   *   the higher resolution to reduce color fringes, making the glyph image
-   *   slightly blurrier.  Positional improvements will remain.
+   *   the stripe (usually horizontal RGB) by a factor of~3.  Using the
+   *   subpixels coverages unfiltered can create severe color fringes
+   *   especially when rendering thin features.  Indeed, to produce
+   *   black-on-white text, the nearby color subpixels must be dimmed
+   *   equally.
    *
-   *   A filter should have two properties:
+   *   A good 5-tap FIR filter should be applied to subpixel coverages
+   *   regardless of pixel boundaries and should have these properties:
    *
-   *   1) It should be normalized, meaning the sum of the 5~components
-   *      should be 256 (0x100).  It is possible to go above or under this
-   *      target sum, however: going under means tossing out contrast, going
-   *      over means invoking clamping and thereby non-linearities that
-   *      increase contrast somewhat at the expense of greater distortion
-   *      and color-fringing.  Contrast is better enhanced through stem
-   *      darkening.
+   *   1. It should be symmetrical, like {~a, b, c, b, a~}, to avoid
+   *      any shifts in appearance.
    *
-   *   2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
-   *      where a~+ b~=~c.  It distributes the computed coverage for one
-   *      subpixel to all subpixels equally, sacrificing some won resolution
-   *      but drastically reducing color-fringing.  Positioning improvements
-   *      remain!  Note that color-fringing can only really be minimized
-   *      when using a color-balanced filter and alpha-blending the glyph
-   *      onto a surface in linear space; see @FT_Render_Glyph.
+   *   2. It should be color-balanced, meaning a~+ b~=~c, to reduce color
+   *      fringes by distributing the computed coverage for one subpixel to
+   *      all subpixels equally.
    *
-   *   Regarding the form, a filter can be a `boxy' filter or a `beveled'
-   *   filter.  Boxy filters are sharper but are less forgiving of non-ideal
-   *   gamma curves of a screen (viewing angles!), beveled filters are
-   *   fuzzier but more tolerant.
+   *   3. It should be normalized, meaning 2a~+ 2b~+ c~=~1.0 to maintain
+   *      overall brightness.
    *
-   *   Examples:
+   *   Boxy 3-tap filter {0, 1/3, 1/3, 1/3, 0} is sharper but is less
+   *   forgiving of non-ideal gamma curves of a screen (and viewing angles),
+   *   beveled filters are fuzzier but more tolerant.
    *
-   *   - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
-   *     normalized.
+   *   Use the @FT_Library_SetLcdFilter or @FT_Library_SetLcdFilterWeights
+   *   API to specify a low-pass filter, which is then applied to
+   *   subpixel-rendered bitmaps generated through @FT_Render_Glyph.
    *
-   *   - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
-   *     normalized.
+   *   Harmony LCD rendering is suitable to panels with any regular subpixel
+   *   structure, not just monitors with 3 color striped subpixels, as long
+   *   as the color subpixels have fixed positions relative to the pixel
+   *   center.  In this case, each color channel is then rendered separately
+   *   after shifting the outline opposite to the subpixel shift so that the
+   *   coverage maps are aligned.  This method is immune to color fringes
+   *   because the shifts do not change integral coverage.
    *
-   *   - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
-   *     balanced.
+   *   The subpixel geometry must be specified by xy-coordinates for each
+   *   subpixel. By convention they may come in the RGB order: {{-1/3, 0},
+   *   {0, 0}, {1/3, 0}} for standard RGB striped panel or {{-1/6, 1/4},
+   *   {-1/6, -1/4}, {1/3, 0}} for a certain PenTile panel.
    *
-   *   - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
-   *     balanced.
+   *   Use the @FT_Library_SetLcdGeometry API to specify subpixel positions.
+   *   If one follows the RGB order convention, the same order applies to the
+   *   resulting @FT_PIXEL_MODE_LCD and @FT_PIXEL_MODE_LCD_V bitmaps.  Note,
+   *   however, that the coordinate frame for the latter must be rotated
+   *   clockwise.  Harmony with default LCD geometry is equivalent to
+   *   ClearType with light filter.
    *
-   *   - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
-   *     balanced.
+   *   As a result of ClearType filtering or Harmony rendering, the
+   *   dimensions of LCD bitmaps can be either wider or taller than the
+   *   dimensions of the corresponding outline with regard to the pixel grid.
+   *   For example, for @FT_RENDER_MODE_LCD, the filter adds 2~subpixels to
+   *   the left, and 2~subpixels to the right.  The bitmap offset values are
+   *   adjusted accordingly, so clients shouldn't need to modify their layout
+   *   and glyph positioning code when enabling the filter.
    *
-   *   - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
-   *     balanced.
+   *   The ClearType and Harmony rendering is applicable to glyph bitmaps
+   *   rendered through @FT_Render_Glyph, @FT_Load_Glyph, @FT_Load_Char, and
+   *   @FT_Glyph_To_Bitmap, when @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V
+   *   is specified.  This API does not control @FT_Outline_Render and
+   *   @FT_Outline_Get_Bitmap.
    *
-   *   The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
-   *   @FT_Load_Glyph, and @FT_Load_Char.  It does _not_ affect the output
-   *   of @FT_Outline_Render and @FT_Outline_Get_Bitmap.
-   *
-   *   If this feature is activated, the dimensions of LCD glyph bitmaps are
-   *   either wider or taller than the dimensions of the corresponding
-   *   outline with regard to the pixel grid.  For example, for
-   *   @FT_RENDER_MODE_LCD, the filter adds 3~subpixels to the left, and
-   *   3~subpixels to the right.  The bitmap offset values are adjusted
-   *   accordingly, so clients shouldn't need to modify their layout and
-   *   glyph positioning code when enabling the filter.
-   *
-   *   It is important to understand that linear alpha blending and gamma
-   *   correction is critical for correctly rendering glyphs onto surfaces
-   *   without artifacts and even more critical when subpixel rendering is
-   *   involved.
-   *
-   *   Each of the 3~alpha values (subpixels) is independently used to blend
-   *   one color channel.  That is, red alpha blends the red channel of the
-   *   text color with the red channel of the background pixel.  The
-   *   distribution of density values by the color-balanced filter assumes
-   *   alpha blending is done in linear space; only then color artifacts
-   *   cancel out.
+   *   The described algorithms can completely remove color artefacts when
+   *   combined with gamma-corrected alpha blending in linear space.  Each of
+   *   the 3~alpha values (subpixels) must by independently used to blend one
+   *   color channel.  That is, red alpha blends the red channel of the text
+   *   color with the red channel of the background pixel.

+   *
+   *   - {{-21, 0}, {0, 0}, {21, 0}} is the default, corresponding to 3 color
+   *   stripes shifted by a third of a pixel. This could be an RGB panel.
+   *
+   *   - {{21, 0}, {0, 0}, {-21, 0}} looks the same as the default but can
+   *   specify a BGR panel instead, while keeping the bitmap in the same
+   *   RGB888 format.
+   *
+   *   - {{0, 21}, {0, 0}, {0, -21}} is the vertical RGB, but the bitmap
+   *   stays RGB888 as a result.
+   *
+   *   - {{-11, 16}, {-11, -16}, {22, 0}} is a certain PenTile arrangement.
+   *
+   *   This function does nothing and returns `FT_Err_Unimplemented_Feature`

+   * This file is used to define the FreeType module error codes.
+   *
+   * If the macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` in `ftoption.h` is
+   * set, the lower byte of an error value identifies the error code as
+   * usual.  In addition, the higher byte identifies the module.  For
+   * example, the error `FT_Err_Invalid_File_Format` has value 0x0003, the
+   * error `TT_Err_Invalid_File_Format` has value 0x1303, the error
+   * `T1_Err_Invalid_File_Format` has value 0x1403, etc.
+   *
+   * Note that `FT_Err_Ok`, `TT_Err_Ok`, etc. are always equal to zero,
+   * including the high byte.
+   *
+   * If `FT_CONFIG_OPTION_USE_MODULE_ERRORS` isn't set, the higher byte of an
+   * error value is set to zero.
+   *
+   * To hide the various `XXX_Err_` prefixes in the source code, FreeType
+   * provides some macros in `fttypes.h`.
+   *
+   *   FT_ERR( err )
+   *
+   *     Add current error module prefix (as defined with the `FT_ERR_PREFIX`
+   *     macro) to `err`.  For example, in the BDF module the line
+   *
+   *     ```
+   *       error = FT_ERR( Invalid_Outline );
+   *     ```
+   *
+   *     expands to
+   *
+   *     ```
+   *       error = BDF_Err_Invalid_Outline;
+   *     ```
+   *
+   *     For simplicity, you can always use `FT_Err_Ok` directly instead of
+   *     `FT_ERR( Ok )`.
+   *
+   *   FT_ERR_EQ( errcode, err )
+   *   FT_ERR_NEQ( errcode, err )
+   *
+   *     Compare error code `errcode` with the error `err` for equality and
+   *     inequality, respectively.  Example:
+   *
+   *     ```
+   *       if ( FT_ERR_EQ( error, Invalid_Outline ) )
+   *         ...
+   *     ```
+   *
+   *     Using this macro you don't have to think about error prefixes.  Of
+   *     course, if module errors are not active, the above example is the
+   *     same as
+   *
+   *     ```
+   *       if ( error == FT_Err_Invalid_Outline )
+   *         ...
+   *     ```
+   *
+   *   FT_ERROR_BASE( errcode )
+   *   FT_ERROR_MODULE( errcode )
+   *
+   *     Get base error and module error code, respectively.
+   *
+   * It can also be used to create a module error message table easily with
+   * something like
+   *
+   * ```
+   *   #undef FTMODERR_H_
+   *   #define FT_MODERRDEF( e, v, s )  { FT_Mod_Err_ ## e, s },
+   *   #define FT_MODERR_START_LIST     {
+   *   #define FT_MODERR_END_LIST       { 0, 0 } };
+   *
+   *   const struct
+   *   {
+   *     int          mod_err_offset;

+   * object, in order to speed up font re-opening time.  Of course, this
+   * feature is purely optional, so most client programs won't even notice
+   * it.
+   *
+   * I initially thought that it would be a good idea to cache the glyph
+   * hints too.  However, my general idea now is that if you really need to
+   * cache these too, you are simply in need of a new font format, where all
+   * this information could be stored within the font file and decoded on the
+   * fly.

+   *
+   * @description:
+   *   The font driver class.  This structure mostly contains pointers to
+   *   driver methods.
+   *
+   * @fields:
+   *   root ::
+   *     The parent module.
+   *
+   *   face_object_size ::
+   *     The size of a face object in bytes.
+   *
+   *   size_object_size ::
+   *     The size of a size object in bytes.
+   *
+   *   slot_object_size ::
+   *     The size of a glyph object in bytes.
+   *
+   *   init_face ::
+   *     The format-specific face constructor.
+   *
+   *   done_face ::
+   *     The format-specific face destructor.
+   *
+   *   init_size ::
+   *     The format-specific size constructor.
+   *
+   *   done_size ::
+   *     The format-specific size destructor.
+   *
+   *   init_slot ::
+   *     The format-specific slot constructor.
+   *
+   *   done_slot ::
+   *     The format-specific slot destructor.
+   *
+   *
+   *   load_glyph ::
+   *     A function handle to load a glyph to a slot.  This field is
+   *     mandatory!
+   *
+   *   get_kerning ::
+   *     A function handle to return the unscaled kerning for a given pair of
+   *     glyphs.  Can be set to 0 if the format doesn't support kerning.
+   *
+   *   attach_file ::
+   *     This function handle is used to read additional data for a face from
+   *     another file/stream.  For example, this can be used to add data from
+   *     AFM or PFM files on a Type 1 face, or a CIDMap on a CID-keyed face.
+   *
+   *   get_advances ::
+   *     A function handle used to return advance widths of 'count' glyphs
+   *     (in font units), starting at 'first'.  The 'vertical' flag must be
+   *     set to get vertical advance heights.  The 'advances' buffer is
+   *     caller-allocated.  The idea of this function is to be able to
+   *     perform device-independent text layout without loading a single
+   *     glyph image.
+   *
+   *   request_size ::
+   *     A handle to a function used to request the new character size.  Can
+   *     be set to 0 if the scaling done in the base layer suffices.
+   *
+   *   select_size ::
+   *     A handle to a function used to select a new fixed size.  It is used
+   *     only if @FT_FACE_FLAG_FIXED_SIZES is set.  Can be set to 0 if the
+   *     scaling done in the base layer suffices.
+   * @note:
+   *   Most function pointers, with the exception of `load_glyph`, can be set
+   *   to 0 to indicate a default behaviour.

+   *   These fields may change between different releases of FreeType.
+   *
+   * @fields:
+   *   max_points ::
+   *     The maximum number of points used to store the vectorial outline of
+   *     any glyph in this face.  If this value cannot be known in advance,
+   *     or if the face isn't scalable, this should be set to 0.  Only
+   *     relevant for scalable formats.
+   *
+   *   max_contours ::
+   *     The maximum number of contours used to store the vectorial outline
+   *     of any glyph in this face.  If this value cannot be known in
+   *     advance, or if the face isn't scalable, this should be set to 0.
+   *     Only relevant for scalable formats.
+   *
+   *   transform_matrix ::
+   *     A 2x2 matrix of 16.16 coefficients used to transform glyph outlines
+   *     after they are loaded from the font.  Only used by the convenience
+   *     functions.
+   *
+   *   transform_delta ::
+   *     A translation vector used to transform glyph outlines after they are
+   *     loaded from the font.  Only used by the convenience functions.
+   *
+   *   transform_flags ::
+   *     Some flags used to classify the transform.  Only used by the
+   *     convenience functions.
+   *
+   *   services ::
+   *     A cache for frequently used services.  It should be only accessed
+   *     with the macro `FT_FACE_LOOKUP_SERVICE`.
+   *
+   *   incremental_interface ::
+   *     If non-null, the interface through which glyph data and metrics are
+   *     loaded incrementally for faces that do not provide all of this data
+   *     when first opened.  This field exists only if
+   *     @FT_CONFIG_OPTION_INCREMENTAL is defined.
+   *
+   *   no_stem_darkening ::
+   *     Overrides the module-level default, see @stem-darkening[cff], for
+   *     example.  FALSE and TRUE toggle stem darkening on and off,
+   *     respectively, value~-1 means to use the module/driver default.
+   *
+   *   random_seed ::
+   *     If positive, override the seed value for the CFF 'random' operator.
+   *     Value~0 means to use the font's value.  Value~-1 means to use the
+   *     CFF driver's default.
+   *
+   *   lcd_weights ::
+   *   lcd_filter_func ::
+   *     These fields specify the LCD filtering weights and callback function
+   *     for ClearType-style subpixel rendering.
+   *
+   *   refcount ::
+   *     A counter initialized to~1 at the time an @FT_Face structure is
+   *     created.  @FT_Reference_Face increments this counter, and
+   *     @FT_Done_Face only destroys a face if the counter is~1, otherwise it
+   *     simply decrements it.

+   *   The FreeType library class.  This is the root of all FreeType data.
+   *   Use FT_New_Library() to create a library object, and FT_Done_Library()
+   *   to discard it and all child objects.
+   *
+   * @fields:
+   *   memory ::
+   *     The library's memory object.  Manages memory allocation.
+   *
+   *   version_major ::
+   *     The major version number of the library.
+   *
+   *   version_minor ::
+   *     The minor version number of the library.
+   *
+   *   version_patch ::
+   *     The current patch level of the library.
+   *
+   *   num_modules ::
+   *     The number of modules currently registered within this library.
+   *     This is set to 0 for new libraries.  New modules are added through
+   *     the FT_Add_Module() API function.
+   *
+   *   modules ::
+   *     A table used to store handles to the currently registered
+   *     modules. Note that each font driver contains a list of its opened
+   *     faces.
+   *
+   *   renderers ::
+   *     The list of renderers currently registered within the library.
+   *
+   *   cur_renderer ::
+   *     The current outline renderer.  This is a shortcut used to avoid
+   *     parsing the list on each call to FT_Outline_Render().  It is a
+   *     handle to the current renderer for the FT_GLYPH_FORMAT_OUTLINE
+   *     format.
+   *
+   *   auto_hinter ::
+   *     The auto-hinter module interface.
+   *
+   *   debug_hooks ::
+   *     An array of four function pointers that allow debuggers to hook into
+   *     a font format's interpreter.  Currently, only the TrueType bytecode
+   *     debugger uses this.
+   *
+   *   lcd_weights ::
+   *     The LCD filter weights for ClearType-style subpixel rendering.
+   *
+   *   lcd_filter_func ::
+   *     The LCD filtering callback function for for ClearType-style subpixel
+   *     rendering.
+   *
+   *   lcd_geometry ::
+   *     This array specifies LCD subpixel geometry and controls Harmony LCD
+   *     rendering technique, alternative to ClearType.
+   *
+   *   pic_container ::
+   *     Contains global structs and tables, instead of defining them
+   *     globally.
+   *
+   *   refcount ::
+   *     A counter initialized to~1 at the time an @FT_Library structure is
+   *     created.  @FT_Reference_Library increments this counter, and
+   *     @FT_Done_Library only destroys a library if the counter is~1,
+   *     otherwise it simply decrements it.

+   *   which is not covered by the generic @FT_CharMap structure.  This
+   *   structure can be accessed with the @FT_Get_TT_CMap_Info function.
+   *
+   * @fields:
+   *   language ::
+   *     The language ID used in Mac fonts.  Definitions of values are in
+   *     `ttnameid.h`.
+   *
+   *   format ::
+   *     The cmap format.  OpenType 1.6 defines the formats 0 (byte encoding
+   *     table), 2~(high-byte mapping through table), 4~(segment mapping to
+   *     delta values), 6~(trimmed table mapping), 8~(mixed 16-bit and 32-bit
+   *     coverage), 10~(trimmed array), 12~(segmented coverage), 13~(last
+   *     resort font), and 14 (Unicode Variation Sequences).

+   *     top-most of all glyph points found in the font.
+   *
+   *     This value is invalid in many fonts, as it is usually set by the

+   *   Descender ::
+   *     The font's descender, i.e., the distance from the baseline to the
+   *     bottom-most of all glyph points found in the font.  It is negative.

+   *   Line_Gap ::
+   *     The font's line gap, i.e., the distance to add to the ascender and
+   *     descender to get the BTB, i.e., the baseline-to-baseline distance
+   *     for the font.
+   *
+   *   advance_Width_Max ::
+   *     This field is the maximum of all advance widths found in the font.
+   *     It can be used to compute the maximum width of an arbitrary string
+   *     of text.
+   *

+   *   min_Right_Side_Bearing ::
+   *     The minimum right side bearing of all glyphs within the font.
+   *
+   *   xMax_Extent ::
+   *     The maximum horizontal extent (i.e., the 'width' of a glyph's
+   *     bounding box) for all glyphs in the font.
+   *
+   *   caret_Slope_Rise ::
+   *     The rise coefficient of the cursor's slope of the cursor
+   *     (slope=rise/run).
+   *
+   *   caret_Slope_Run ::
+   *     The run coefficient of the cursor's slope.
+   *
+   *   caret_Offset ::
+   *     The cursor's offset for slanted fonts.
+   *
+   *   Reserved ::
+   *     8~reserved bytes.
+   *
+   *   metric_Data_Format ::
+   *     Always~0.
+   *
+   *   number_Of_HMetrics ::
+   *     Number of HMetrics entries in the 'hmtx' table -- this value can be
+   *     smaller than the total number of glyphs in the font.

+   *   long_metrics ::

+   *
+   * @fields:
+   *   Version ::
+   *     The table version.
+   *
+   *   Ascender ::
+   *     The font's ascender, i.e., the distance from the baseline to the
+   *     top-most of all glyph points found in the font.
+   *
+   *     This value is invalid in many fonts, as it is usually set by the

+   *     You should use the `sTypoAscender` field of the 'OS/2' table instead
+   *     if you want the correct one.
+   *
+   *   Descender ::
+   *     The font's descender, i.e., the distance from the baseline to the
+   *     bottom-most of all glyph points found in the font.  It is negative.
+   *
+   *     This value is invalid in many fonts, as it is usually set by the

+   *     You should use the `sTypoDescender` field of the 'OS/2' table
+   *     instead if you want the correct one.
+   *
+   *   Line_Gap ::
+   *     The font's line gap, i.e., the distance to add to the ascender and
+   *     descender to get the BTB, i.e., the baseline-to-baseline distance
+   *     for the font.
+   *
+   *   advance_Height_Max ::
+   *     This field is the maximum of all advance heights found in the font.
+   *     It can be used to compute the maximum height of an arbitrary string
+   *     of text.
+   *
+   *   min_Top_Side_Bearing ::
+   *     The minimum top side bearing of all glyphs within the font.
+   *
+   *   min_Bottom_Side_Bearing ::
+   *     The minimum bottom side bearing of all glyphs within the font.
+   *
+   *   yMax_Extent ::
+   *     The maximum vertical extent (i.e., the 'height' of a glyph's
+   *     bounding box) for all glyphs in the font.
+   *
+   *   caret_Slope_Rise ::
+   *     The rise coefficient of the cursor's slope of the cursor
+   *     (slope=rise/run).
+   *
+   *   caret_Slope_Run ::
+   *     The run coefficient of the cursor's slope.
+   *
+   *   caret_Offset ::
+   *     The cursor's offset for slanted fonts.
+   *
+   *   Reserved ::
+   *     8~reserved bytes.
+   *
+   *   metric_Data_Format ::
+   *     Always~0.
+   *
+   *   number_Of_VMetrics ::
+   *     Number of VMetrics entries in the 'vmtx' table -- this value can be
+   *     smaller than the total number of glyphs in the font.
+   *
+   *   long_metrics ::
+   *     A pointer into the 'vmtx' table.
+   *
+   *   short_metrics ::
+   *     A pointer into the 'vmtx' table.

-   *  non-standard glyph indices (features get used for other things also).
-   *  For example, the `sups' feature provides superscript glyphs, thus
-   *  mapping character codes like `A' or `B' to superscript glyph
-   *  representation forms.  How this mapping happens is completely
-   *  uninteresting to us.
+   * In the OpenType world, a better solution was invented, namely
+   * `features', which cleanly separate a character's input encoding from
+   * the corresponding glyph's appearance, and which don't use glyph names
+   * at all.  For our purposes, and slightly generalized, an OpenType

-   *  For the auto-hinter, a `coverage' represents all glyphs of an OpenType
-   *  feature collected in a set (as listed below) that can be hinted

+   *
+   *       o a direction, indicating whether it was built going `up' or
+   *         `down', as this is very important for filling rules
+   *
+   *       o its drop-out mode
+   *
+   *   2 - Sweeping the target map's scanlines in order to compute segment
+   *       `spans' which are then filled.  Additionally, this pass
+   *       performs drop-out control.

+   *   bottom-most scanline as well as the scanline above its upmost
+   *   boundary.  These positions are called `y-turns' because they (sort
+   *   of) correspond to local extrema.  They are stored in a sorted list
+   *   built from the top of the render pool as a downwards stack:

+         * Computing the ascender/descender/height is tricky.
+         *
+         * The OpenType specification v1.8.3 says:
+         *
+         *   [OS/2's] sTypoAscender, sTypoDescender and sTypoLineGap fields
+         *   are intended to allow applications to lay out documents in a
+         *   typographically-correct and portable fashion.
+         *
+         * This is somewhat at odds with the decades of backwards
+         * compatibility, operating systems and applications doing whatever
+         * they want, not to mention broken fonts.
+         *
+         * Not all fonts have an OS/2 table; in this case, we take the values
+         * in the horizontal header, although there is nothing stopping the
+         * values from being unreliable. Even with a OS/2 table, certain fonts
+         * set the sTypoAscender, sTypoDescender and sTypoLineGap fields to 0
+         * and instead correctly set usWinAscent and usWinDescent.
+         *
+         * As an example, Arial Narrow is shipped as four files ARIALN.TTF,
+         * ARIALNI.TTF, ARIALNB.TTF and ARIALNBI.TTF. Strangely, all fonts have
+         * the same values in their sTypo* fields, except ARIALNB.ttf which
+         * sets them to 0. All of them have different usWinAscent/Descent
+         * values. The OS/2 table therefore cannot be trusted for computing the
+         * text height reliably.
+         *
+         * As a compromise, do the following:
+         *
+         * 1. If the OS/2 table exists and the fsSelection bit 7 is set
+         *    (USE_TYPO_METRICS), trust the font and use the sTypo* metrics.
+         * 2. Otherwise, use the `hhea' table's metrics.
+         * 3. If they are zero and the OS/2 table exists,
+         *    1. use the OS/2 table's sTypo* metrics if they are non-zero.
+         *    2. Otherwise, use the OS/2 table's usWin* metrics.

+   *   glyphIds      16+NUM_SEGS*8  USHORT[]          array of glyph ID
+   *                                                  ranges
+   *
+   * Character codes are modelled by a series of ordered (increasing)
+   * intervals called segments.  Each segment has start and end codes,
+   * provided by the `startCount' and `endCount' arrays.  Segments must
+   * not overlap, and the last segment should always contain the value
+   * 0xFFFF for `endCount'.
+   *
+   * The fields `searchRange', `entrySelector' and `rangeShift' are better
+   * ignored (they are traces of over-engineering in the TrueType
+   * specification).
+   *
+   * Each segment also has a signed `delta', as well as an optional offset
+   * within the `glyphIds' table.
+   *
+   * If a segment's idOffset is 0, the glyph index corresponding to any
+   * charcode within the segment is obtained by adding the value of
+   * `idDelta' directly to the charcode, modulo 65536.
+   *
+   * Otherwise, a glyph index is taken from the glyph IDs sub-array for
+   * the segment, and the value of `idDelta' is added to it.
+   *
+   *
+   * Finally, note that a lot of fonts contain an invalid last segment,
+   * where `start' and `end' are correctly set to 0xFFFF but both `delta'
+   * and `offset' are incorrect (e.g., `opens___.ttf' which comes with
+   * OpenOffice.org).  We need special code to deal with them correctly.

+   *
+   * This is a new anti-aliasing scan-converter for FreeType 2.  The
+   * algorithm used here is _very_ different from the one in the standard
+   * `ftraster' module.  Actually, `ftgrays' computes the _exact_
+   * coverage of the outline on each pixel cell by straight segments.
+   *
+   * It is based on ideas that I initially found in Raph Levien's
+   * excellent LibArt graphics library (see https://www.levien.com/libart
+   * for more information, though the web pages do not tell anything
+   * about the renderer; you'll have to dive into the source code to
+   * understand how it works).
+   *
+   * Note, however, that this is a _very_ different implementation
+   * compared to Raph's.  Coverage information is stored in a very
+   * different way, and I don't use sorted vector paths.  Also, it doesn't
+   * use floating point values.
+   *
+   * Bézier segments are flattened by splitting them until their deviation
+   * from straight line becomes much smaller than a pixel.  Therefore, the
+   * pixel coverage by a Bézier curve is calculated approximately.  To
+   * estimate the deviation, we use the distance from the control point
+   * to the conic chord centre or the cubic chord trisection.  These
+   * distances vanish fast after each split.  In the conic case, they vanish
+   * predictably and the number of necessary splits can be calculated.
+   *
+   * This renderer has the following advantages:
+   *
+   * - It doesn't need an intermediate bitmap.  Instead, one can supply a
+   *   callback function that will be called by the renderer to draw gray
+   *   spans on any target surface.  You can thus do direct composition on
+   *   any kind of bitmap, provided that you give the renderer the right
+   *   callback.
+   *
+   * - A perfect anti-aliaser, i.e., it computes the _exact_ coverage on
+   *   each pixel cell by straight segments.
+   *
+   * - It performs a single pass on the outline (the `standard' FT2
+   *   renderer makes two passes).
+   *
+   * - It can easily be modified to render to _any_ number of gray levels
+   *   cheaply.
+   *
+   * - For small (< 80) pixel sizes, it is faster than the standard
+   *   renderer.

-
-ftfuzzer.cc
------------
-
-This file contains a target function  for FreeType fuzzing.  It can be
-used   with    libFuzzer   (https://llvm.org/docs/LibFuzzer.html)   or
-potentially any other similar fuzzer.
-
-Usage:
-
-  1. Build  `libfreetype.a' and  `ftfuzzer.cc' using  the most  recent
-     clang compiler with these flags:
-
-       # for fuzzer coverage feedback
-       -fsanitize-coverage=edge,8bit-counters
-       # for bug checking
-       -fsanitize=address,signed-integer-overflow,shift
-
-     You  also need  the header  files from  the `libarchive'  library
-     (https://www.libarchive.org/)  for handling  tar files  (see file
-     `ftmutator.cc' below for more).
-
-  2. Link with `libFuzzer' (it contains `main') and `libarchive'.
-
-  3. Run the fuzzer on some test corpus.
-
-The exact flags and commands may vary.
-
-  https://github.com/google/oss-fuzz/tree/master/projects/freetype2
-
-There is a continuous fuzzing bot that runs ftfuzzer.
-
-  https://oss-fuzz.com
-
-(You need an account  to be able to see coverage  reports and the like
-on oss-fuzz.com.)
-
-Check the bot configuration for the most current settings.
-
-
-ftmutator.cc
-------------
-
-FreeType has the  ability to `attach' auxiliary files to  a font file,
-providing additional information.  The main usage is to load AFM files
-for PostScript Type 1 fonts.
-
-However, libFuzzer currently only supports  mutation of a single input
-file.   For  this  reason,  `ftmutator.cc' contains  a  custom  fuzzer
-mutator that uses an uncompressed tar  file archive as the input.  The
-first file in  such a tarball gets  opened by FreeType as  a font, all
-other files are treated as input for `FT_Attach_Stream'.
-
-Compilation is similar to `ftfuzzer.c'.
-
-
-runinput.cc
------------
-
-To run the target function on a set of input files, this file contains
-a   convenience  `main'   function.   Link   it  with   `ftfuzzer.cc',
-`libfreetype.a', and `libarchive' and run like
-
-  ./a.out my_tests_inputs/*

+   *
+   * @Description:
+   *   A driver method used to load a glyph within a given glyph slot.
+   *
+   * @Input:
+   *   slot ::
+   *     A handle to the target slot object where the glyph
+   *     will be loaded.
+   *
+   *   size ::
+   *     A handle to the source face size at which the glyph
+   *     must be scaled, loaded, etc.
+   *
+   *   glyph_index ::
+   *     The index of the glyph in the font file.
+   *
+   *   load_flags ::
+   *     A flag indicating what to load for this glyph.  The
+   *     FT_LOAD_XXX constants can be used to control the
+   *     glyph loading process (e.g., whether the outline
+   *     should be scaled, whether to load bitmaps or not,
+   *     whether to hint the outline, etc).
+   *
+   * @Return:

+   * A note regarding non-squared pixels:
+   *
+   * (This text will probably go into some docs at some time; for now, it
+   * is kept here to explain some definitions in the TT_Size_Metrics
+   * record).
+   *
+   * The CVT is a one-dimensional array containing values that control
+   * certain important characteristics in a font, like the height of all
+   * capitals, all lowercase letter, default spacing or stem width/height.
+   *
+   * These values are found in FUnits in the font file, and must be scaled
+   * to pixel coordinates before being used by the CVT and glyph programs.
+   * Unfortunately, when using distinct x and y resolutions (or distinct x
+   * and y pointsizes), there are two possible scalings.
+   *
+   * A first try was to implement a `lazy' scheme where all values were
+   * scaled when first used.  However, while some values are always used
+   * in the same direction, some others are used under many different
+   * circumstances and orientations.
+   *
+   * I have found a simpler way to do the same, and it even seems to work
+   * in most of the cases:
+   *
+   * - All CVT values are scaled to the maximum ppem size.
+   *
+   * - When performing a read or write in the CVT, a ratio factor is used
+   *   to perform adequate scaling.  Example:
+   *
+   *     x_ppem = 14
+   *     y_ppem = 10
+   *
+   *   We choose ppem = x_ppem = 14 as the CVT scaling size.  All cvt
+   *   entries are scaled to it.
+   *
+   *     x_ratio = 1.0
+   *     y_ratio = y_ppem/ppem (< 1.0)
+   *
+   *   We compute the current ratio like:
+   *
+   *   - If projVector is horizontal,
+   *       ratio = x_ratio = 1.0
+   *
+   *   - if projVector is vertical,
+   *       ratio = y_ratio
+   *
+   *   - else,
+   *       ratio = sqrt( (proj.x * x_ratio) ^ 2 + (proj.y * y_ratio) ^ 2 )
+   *
+   *   Reading a cvt value returns
+   *     ratio * cvt[index]
+   *
+   *   Writing a cvt value in pixels:
+   *     cvt[index] / ratio
+   *
+   *   The current ppem is simply
+   *     ratio * ppem
+   *
