    Move `scripts/make_distribution_archives.py` to `src/tools`.

    * scr/tools/scripts/make_distribution_archives.py: (_TOP_DIR,
    _SCRIPT_DIR): Updated to new location.
    (main): s/shutils.copyfile/shutils.copy/ to preserve file
    permissions.
    (main): Prefix source file paths with `git_dir` while copying files
    to allow calls of the script from other places than the top-level
    directory.

Date:   Thu Sep 24 09:35:24 2020 +0200

    * src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`.

    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>.

    [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

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).

    [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.

    [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.

    Add .clang-format file

    This file can be used to reformat FreeType sources and commits
    using one of these methods:

    - Direct formatting of a whole file:

        clang-format -i path/to/file

      For example, to reformat all sources at once:

        echo builds/unix/ftconfig.h.in $(git ls-files *.[hc]) | xargs clang-format -i

    - Only reformat the changed lines in the current work directoy:

        git clang-format

    The style settings in this file are very close to the FreeType
    formatting style, with the following exceptions which are not supported
    here:

    - Mminimal 2-space margin on each non-empty line.
      (no left margin instead).

    - 2 empty lines between variable declarations and statements in C blocks.
      (only 1 is kept).

        {
          int  x = ...;

          foo(x);
        }

      becomes

    - 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)

    Document `FT_Face_Rec_::box' with variable fonts (#54969).

    As pointed out in the "Note:" in the section of

      https://docs.microsoft.com/en-us/typography/opentype/spec/otvaroverview#variation-data-tables-and-miscellaneous-requirements

      ... the xMin, yMin, xMax, yMax, macStyle and lowestRecPPEM fields in
      the font header ('head') table are not supported by variation data and
      should only be used in relation to the default instance for the font.

    Document that `FT_Face_Rec_::box' does not vary with OpenType variable
    fonts.

    [build] Really fix multi and C++ builds.

    The following builds were still failing due to previous changes:

      make multi
      make multi CC="c++"
      make CC="c++"

    This patch fixes the issues, which were missing includes to get the
    right macro definitions in multi-build mode.

    Also, `FT_UNUSED' is actually used by third-party code, so move it
    back to `public-macros.h' to avoid breaking it.

    * include/freetype/config/public-macros.h (FT_EXPORT): Remove
    special definition for C++.
    (FT_UNUSED): Define here instead of...
    * include/freetype/config/compiler-macros.h: ... here.
    (FT_FUNCTION_DECLARATION): Remove special definition for C++.
    (FT_LOCAL_ARRAY_DEF): Fix definition.

    * src/cache/ftccback.h, src/lzw/ftzopen.h, src/gxvalid/gxvmort.h,
    src/gxvalid/gxvmorx.h: Add `FT_BEGIN_HEADER' and `FT_END_HEADER'.

    [build] Improve visibility support of library function names.

    * include/freetype/config/public-macros.h
    (FT_PUBLIC_FUNCTION_ATTRIBUTE): New macro to tag functions as
    public (and thus exportable).
    (FT_EXPORT): Use it.

    * include/freetype/config/compiler-macros.h
    (FT_INTERNAL_FUNCTION_ATTRIBUTE): New macro to tag functions as
    internal to the library (and thus hidden).  Note that on ELF
    systems, all internal functions have hidden visibility, which avoids
    the need to enforce this when invoking the compiler (e.g., with an
    option like `-fvisibility=hidden').

    (FT_FUNCTION_DECLARATION, FT_FUNCTION_DEFINITION): New base macros
    to deal with C and C++ linkage issues at the same time.

    (FT_LOCAL, FT_LOCAL_DEF, FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF,
    FT_BASE, FT_BASE_DEF, FT_EXPORT_VAR, FT_BASE_CALLBACK,
    FT_BASE_CALLBACK_DEF): Redefined using new macros.

    [build] Put integer type definitions into `integer-types.h'.

    Refactor some of the `ftconfig.h' headers and template to move the
    definition of the FreeType integer types (e.g., `FT_Int16') to a
    common header file `freetype/config/integer-types.h'.

    * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
    include/freetype/config/ftconfig.h: Split off integer type
    definition stuff to...
    * include/freetype/config/integer-types.h: ...this new file.

    * builds/unix/ftconfig.h.in: Control the definition of
    `FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro
    `FT_USE_AUTOCONF_SIZEOF_TYPES'.  If these are not defined, auto
    detection happens in `integer-types.h' as usual based on `INTXX_MAX'
    values.  Otherwise the autoconf-detected values are used.

    * builds/unix/configure.raw (CPPFLAGS): Don't include path to
    `config' directory.  Instead, ...
    (FT_CONFIG_STANDARD_LIBRARY_H): Use complete path.

    Since we are no longer limited to 8.3 file names, it is simpler to
    follow the usual conventions for template files.

    * builds/unix/ftconfig.in: Renamed to...
    * builds/unix/ftconfig.h.in: ...this.

    [smooth] Introduce direct oversampling for overlaps.

    This implements oversampling to metigate artifacts in pixels partially
    covered by overlapping contours.  It turns out that the 4x4
    oversampling is sufficient but, at least, quadruples the rendering
    time.  The outline has to set FT_OUTLINE_OVERLAP to use this method.

    * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): New flag.
    * src/smooth/ftsmooth.c (ft_smooth_render): Check it to...
    (ft_smooth_raster_overlap): ... inflate outline and set up direct
    rendering for oversampling with...
    (ft_smooth_overlap_spans): ... new span function that integrates them.

    [smooth] Use direct rendering mode in Harmony.

    Instead of rendering 3 bitmaps side by side and reshuffling, we use
    direct rendering to deliver the bitmaps on each third byte.

    * src/smooth/ftsmooth.c (ft_smooth_raster_lcd)
    [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Set up direct mode with...
    (ft_smooth_lcd_spans): ... new span function.

    [smooth] Separate LCD paths from gray rendering.

    This makes `ft_smooth_render' a lot smaller and easier to follow. It
    also cleanly separates Harmony and ClearType-style LCD rendering
    algorithms. Now I only wish to move LCD filtering and geometry from
    FT_Library to FT_Renderer.

    * src/smooth/ftsmooth.c (ft_smooth_render): Move LCD code from here...
    (ft_smooth_raster_lcd, ft_smooth_raster_lcdv): ... to here.
    [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Reorganize #ifdef's.

    [cff] Fix handling of `style_name == NULL' (#58630).

    * src/cff/cffobjs.c (cff_face_init): If a call to `cff_strcpy' fails
    by returning NULL in `cff_face_init', `remove_style' is still
    called.  This means that the NULL pointer is dereferenced, causing a
    crash.

    We no longer have to take care of the 8.3 file name limit; this
    allows us (a) to introduce longer, meaningful file names, and (b) to

    compilers (most notably Visual C++) doesn't support this properly.

    [smooth] Stop using dedicated LCD modules and classes.

    The LCD modules were never truly independent. They mostly served as
    a way to disable patented LCD rendering, which is no longer necessary.
    The `smooth' module now handles LCD modes as well.

    * src/smooth/ftsmooth.c (ft_smooth_lcd_renderer_class.
    ft_smooth_lcdv_renderer_class): Deleted.

    [gzip] Support `gzip' encoded header conditionally.

    In order to support `gzip' encoded header the call to
    `inflateInit2' was modified in commit 6a92b1fadde26477a9179.
    However, this code breaks with the outdated internal version
    of zlib.  This is a temporary fix to conditionally support
    `gzip' encoded header whenever a system installation of zlib
    is being used.

    Problem report in

      https://lists.nongnu.org/archive/html/freetype-devel/2020-02/msg00023.html

    * src/gzip/ftgzip.c (FT_Gzip_Uncompress): Change the the call to
    `inflateInit2' depending on whether the system installation is
    being used or the internal copy.

    Fix state of `FT_Face' for buggy `gvar' tables (#57923).

    By resetting the blend as implemented with this commit fonts with
    invalid `gvar' tables may keep calling into `ft_var_load_gvar' from
    `tt_set_mm_blend' and failing, but the font was invalid anyway and
    we want to keep seeing the failure in `tt_set_mm_blend'.

    * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of
    offset array once.
    Allocate arrays after `FT_FRAME_ENTER' (extra check before
    allocating and avoid needing to free array later if error entering
    frame).
    Always call `FT_FRAME_EXIT'.
    Consistently set counts immediately after array initialized.
    Reset the blend (particularly `blend->glyphoffsets') on failure.

    [cmake] Don't fail if brotli is missing (#56894).

    The libs which cmake controls are commented out at

      include/freetype/config/ftoption.h

    and cmake un-comment each enabled library, but the brotli option was
    not commented out, therefore `FT_CONFIG_OPTION_USE_BROTLI' remained
    defined even if brotli was missing/disabled/etc.

    Comment it such that cmake can control it, which means leaving it
    undefined if brotli is missing.

    [woff2] Support `hmtx' reconstruction when `glyf' is untransformed.

    `reconstruct_hmtx' requires `info->x_mins' and `info->num_glyphs' to
    reconstruct the hmtx table.  In case glyf is not transformed, we
    call `get_x_mins' which does the necessary work.

    * src/sfnt/sfwoff2.c (get_x_mins): New function.
    (reconstruct_font): Call get_x_mins.

    [sfnt] Support `face->num_faces' for WOFF2 fonts.

    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'.
    (sfnt_init_face): Introduce variable `woff2_num_faces', and change
    `face->root.num_faces' if `woff2_num_faces' is set.

    * src/sfnt/sfwoff2.c (woff2_open_font): Validate requested face
    index and handle negative face indices.

    * src/sfnt/sfwoff2.h (woff2_open_font): Add parameter `num_faces' to

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

    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.

    [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

    (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'.

    table stream.  Also add necessary structures, macros and functions.

    * include/freetype/internal/wofftypes.h (WOFF2_InfoRec,

    (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.

    (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'.

    [woff2] Uncompress Brotli streams and `face_index' support.

    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'.

    [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>:

    [smooth] Restore the span buffering for direct mode only.

    The buffer size FT_MAX_GRAY_SPANS is set to 10 spans, which should be
    enough to cover the entire scanline for simple glyphs in most cases:
    each slightly slanted edge needs up to two spans, plus a filling span
    in-between.  This is not new, we used to do it before cb4388783cecc.

    * src/smooth/ftgrays.c (gray_TWorker): Add `spans' and `num_spans'.
    (gray_hline, gray_sweep): Implement the span buffering.
    (gray_raster_render): Use negative `num_spans' to avoid the direct
    mode.

    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.

    [pcf] Fix handling of undefined glyph (#56067).

    This commit fixes the changes from 2018-07-21, which broke charmap
    iteration.  We now add the default character as a new glyph with
    index 0, thus increasing the number of glyphs by one (as before).

    * src/pcf/pcfread.c (pcf_get_metrics): Adjust to new artificial
    glyph with index 0.
    Limit number of elements to 65534.
    (pcf_get_bitmaps): Ditto.
    Unify two loops into one; this avoids allocation of an intermediate
    array.
    (pcf_get_encodings): Don't flip indices but copy glyph metrics of
    default character to index 0.
    Also handle invalid default character.

    * docs/CHANGES: Updated.

    [cff] Fix boundary checks.

    642bc7590c701c8cd35a9f60fa899cfa518b17ff introduced dynamically
    allocated memory when parsing CFF files with the "old" engine.  Bounds
    checks have never been updated, however, leading to pointless
    comparisons of pointers in some cases.  This commit presents a
    solution for bounds checks in the CFF module with an extended logic
    for the "old" engine while staying as concise as possible for the
    "new" one.

    * src/cff/cffparse.h: Introduce the struct `CFF_T2_StringRec' and
    the additional field `t2_strings' within `CFF_ParserRec'.

    * src/cff/cffparse.c (cff_parser_within_limits): Move all boundary
    checks into this new function and update the rest of `cffparse.c' to
    use it.

    * src/psaux/psintrp.c (cf2_interpT2CharString): The call to
    `cf2_arrstack_setCount' may fail because the allocator ran out of

    error condition is checked.  This means that FreeType writes outside
    of allocated memory.  This commit moves the error check prior to the
    stack assignment, hence the function now properly returns with an
    error condition.

    [truetype] Apply MVAR hasc, hdsc and hlgp metrics to current FT_Face metrics.

    Instead of setting typo or win metrics as the new FT_Face metrics
    indiscriminately, apply only typo deltas to the currently active FT_Face
    metrics. This prevents line height differences when e.g. the default
    outlines were used as the regular face and instances for everything else.

    All of the Type 1 path building is done with code common to the

    were not always written to the path, and glyph corruption, or even
    invalid outlines were possible.

    Fix handing of `FT_Bool'.

    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.

    Improve documentation of `FT_LOAD_NO_RECURSE'.

Author: Ben Wagner <bungeman@google.com>

    Improve auto-hinter handling of bitmap fonts (#54681).

    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.

    [truetype] Avoid nested frames.

    Triggered by

      https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10054

    * src/truetype/ttgload.c (load_truetype_glyph): Don't use variable
    `opened_frame' to trace whether a frame must be closed at the end of
    function: This fails because `TT_Vary_Apply_Glyph_Deltas' (which
    gets called for space glyphs) uses a frame by itself.  Instead,
    close the frame after loading the header, then use another frame for
    the remaining part of the glyph later on.

    Also avoid calling `tt_get_metrics' twice under some circumstances.

    [truetype] Increase precision while applying VF deltas.

    It turned out that we incorrectly round CVT and glyph point deltas
    before accumulation, leading to severe positioning errors if there
    are many delta values to sum up.

    Problem reported by Akiem Helmling <akiem@underware.nl> and analyzed
    by Behdad.

    16.16 format.

    functions obsolete because the fields will be directly accessable.

    [smooth] Formalize Harmony LCD rendering.

    This generalizes magic outline shifts that make Harmony LCD
    rendering work in terms of precise two-dimensional RGB subpixel
    positions. These coordinates are now set in time of the `smooth'
    module initialization and later used to shift a glyph outline for
    rendering. FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V use the same
    coordinates. The letter, however, rotates them before using.
    The LCD bitmap padding is also calculated using these coordinates.

    * include/freetype/internal/ftobjs.h (FT_LibraryRec): New array field
    `lcd_geometry'.
    * src/base/ftlcdfil.c (ft_lcd_padding): Reworked.

    [base] Fix mono bitmap presetting (#53896).

    It is rather fundamental to set monochrome bitmap based on rounded
    CBox because the b/w rasterizer turns on pixels when their centers are
    inside the glyph outline. The dropout control is unpredictable and can
    distort narrow glyphs if the bitmap is too wide.

    Reported by Chris Liddell.

    * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): If BBox boundaries
    are too close, adjust them before rounding.

    [sfnt] Preliminary support of coloured layer outlines.

    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.

    There are still some issues with metrics; additionally, an API to
    fetch color layers is missing.

    * devel/ftoption.h, include/freetype/config/ftoption.h
    (TT_CONFIG_OPTION_COLOR_LAYERS): New macro.

    * include/freetype/internal/ftobjs.h (FT_Glyph_LayerRec,
    FT_Colr_InternalRec): New structures.
    (FT_Slot_InternalRec): Add `color_layers' field.

    * include/freetype/internal/sfnt.h (TT_Load_Colr_Layer_Func,
    TT_Blend_Colr_Func): New function types.
    (SFNT_Interface): Add `load_colr', `free_colr', `load_colr_layer',
    and `colr_blend' fields.

    * include/freetype/internal/tttypes.h (TT_FaceRec): Add

    Further fix to visibility flag testing with Solaris Studio compilers.

    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.

    [build] Suppress configure's `nothing to be done' message.

    This is due to calling the configure script via `make' (within the
    top-level `configure' wrapper script).  The same can happen for all
    other secondary make targets that are used to only modify the
    primary one, e.g., `make setup devel'.
