This corresponds to the following commits in the ttfautohint git
repository:
bb6842bd3bd437b7b4a7921b0376c860f5e73d18 Typo, formatting.

commit e8ee98e669c25d0b8e67cdaace9a6b7e49c7a0c0
Author: Werner Lemberg <wl@gnu.org>
Date: Fri Sep 25 07:22:08 2020 +0200
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.
commit 4f13a43ab32ba77793d8528d4b4c057c6f76b835
Author: Werner Lemberg <wl@gnu.org>
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

* 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.

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
{
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)

[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,

[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.

[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...

[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

Make macros for header file names optional.
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
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.
*/*: Replace
#include FOO_H
with
#include <freetype/foo.h>
or something similar. Also update the documentation.

[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.

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.

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

[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.

commit f2b64583cb2587373e126b06d8da9ac97b287681
Author: Chris Liddell <chris.liddell@artifex.com>
Date: Thu Jul 4 14:04:52 2019 +0200
[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] 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.

[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.
* 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.

[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

memory. When this happens the stack is still written to before the
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.

CHANGES: Document recent metrics change from Nikolaus.
commit a6feefdfefd6eb8e62728f40638241bb1d8c993e
Author: Nikolaus Waxweiler <madigens@gmail.com>
Date: Sat Feb 2 15:50:57 2019 +0000
[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.
* src/truetype/ttgxvar.c (tt_apply_mvar): Implement.
commit f72b00746c64e13625cf8371f031411fbd0d6161
Author: Nikolaus Waxweiler <madigens@gmail.com>
Date: Sat Feb 2 15:45:31 2019 +0000
[sfnt] Use typo metrics if OS/2 fsSelection USE_TYPO_METRICS bit is set.
If the OS/2 table exists and fsSelection bit 7 (USE_TYPO_METRICS) is set,
use the sTypo* set of values to compute the FT_Face's ascender, descender
and height. Otherwise, fall back to old behavior.
* src/sfnt/sfobjs.c (sfnt_load_face): Implement.

[psaux] Fix closepath (#55414).
All of the Type 1 path building is done with code common to the
revised CFF engine, with the exception of closepath, which was still
calling ps_builder_close_contour(), thus previously cached segments
were not always written to the path, and glyph corruption, or even
invalid outlines were possible.
* src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>:
Switch to calling `cf2_glyphpath_closeOpenPath'.

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 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.
* src/truetype/ttgxvar.c (ft_var_readpackeddelta): Return deltas in
16.16 format.
(tt_face_var_cvt): Collect deltas in `cvt_deltas', which is a 16.16
format array, and add the accumulated values to the CVT at the end
of the function.
(TT_Vary_Apply_Glyph_Deltas): Store data in `points_org' and
`points_out' in 16.16 format.
Collect deltas in `point_deltas_x' and `point_deltas_y', which are

ftcolor.h: Redesign API.
While going to implement it I noticed that I need access to most of
the `CPAL' elements; I thus plan to add a `cpal' field to
`TT_FaceRec', which makes most of the previously suggested API
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.

* src/smooth/ftsmooth.c [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]

[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,

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.

[autofit] Avoid potential SEGV if running out of memory.
Problem reported by Shailesh Mistry <shailesh.mistry@hotmail.co.uk>.
* src/autofit/afshaper.c (af_shaper_buf_create,
af_shaper_buf_destroy) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Don't
allocate and free a four-byte buffer. Instead, make those functions
no-ops; the calling functions will provide a pointer to a buffer
instead.

af_cjk_metrics_init_blues, af_cjk_metrics_check_digits),
src/autofit/aflatin.c (af_latin_metrics_init_widths,
af_latin_metrics_init_blues, af_latin_metrics_check_digits)
[!FT_CONFIG_OPTION_USE_HARFBUZZ]: Use pointer to local variable for
`shaper_buf'.

[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'.

Support symbol visibility features of Sun / Oracle C compilers.
Reported by Kiyoshi Kanazawa:
https://lists.gnu.org/archive/html/freetype-devel/2018-05/msg00008.html
Thanks to the suggestions by Alexei and Alan Coopersmith.
* builds/unix/configure.raw: Check if "-xldscope=hidden" is
accepted, and if so, it is added to CFLAGS. This is the option
making Sun / Oracle C compilers hide the symbols from global
scope.
* include/freetype/config/ftconfig.h: Use "__global" prefix
for FT_EXPORT() macro, if SunPro C is newer than Sun ONE
Studio 8 (2003).
* builds/unix/ftconfig.in: Ditto.
* builds/vms/ftconfig.h: Ditto.
