This is another bit to handle 'sbix' tables as described in the OpenType
specification.
* include/freetype/ftparams.h (FT_PARAM_TAG_IGNORE_SBIX): New macro.
* src/sfnt/sfobjc.c (is_apple_sbix): Rename to...
(has_sbix): ... this.
Check for more sbit tables.
Handle `FT_PARAM_TAG_IGNORE_SBIX` to eventually control `has_sbix`.
Only call sbit table loader if an sbit table is present.
Fonts with 'sbix' tables need special handling by the application.
* include/freetype/freetype.h (FT_FACE_FLAG_SBIX, FT_HAS_SBIX): New macros.
* src/sfnt/sfobjs.c (sfnt_load_face): Set `FT_FACE_FLAG_SBIX` if 'sbix'
table is present.
`FT_Outline_Decompose` does not filter out and can return degenerate
segments in an outline. This can be surprising when attemping to
stroke such an outline. Clarify the existing documentation on this
matter to cover all forms of degeneracy (without specifying exactly
how they will be reported), why they might arise, and better explain in
what cases they may be an issue.
* include/freetype/ftoutlin.h (FT_Outline_Decompose): update
documentation.
Fixes#952.
* include/freetype/config/ftheader.h (FT_OTSVG_H): New macro.
* include/freetype/freetype.h (FT_FACE_FLAG_SVG, FT_HAS_SVG): New macros.
(FT_LOAD_SVG_ONLY): New internal macro.
* include/freetype/ftimage.h (FT_Glyph_Format): New enumeration value
`FT_GLYPH_FORMAT_SVG`.
* include/freetype/internal/ftobjs.h (FT_GLYPH_OWN_GZIP_SVG): New macro.
* include/freetype/internal/fttrace.h: Add `ttsvg` for `ttsvg.c`.
* include/freetype/internal/sfnt.h(load_svg, free_svg, load_svg_doc): New
functions.
* include/freetype/internal/tttypes.h (TT_FaceRec): Add `svg` for
the SVG table.
* include/freetype/otsvg.h (FT_SVG_DocumentRec): New structure to hold the
SVG document and other necessary information of an OT-SVG glyph in a glyph
slot.
* include/freetype/tttags.h (TTAG_SVG): New macro.
* src/base/ftobjs.c: Include `otsvg.h`.
(ft_glyphslot_init): Allocate `FT_SVG_DocumentRec` in `slot->other`
if the SVG table exists.
(ft_glyphslot_clear): Free it upon clean-up if it is a GZIP compressed
glyph.
(ft_glyphslot_done): Free the document data if it is a GZIP compressed
glyph.
(FT_Load_Glyph): Don't auto-hint SVG documents.
* src/cache/ftcbasic.c (ftc_basic_family_load_glyph): Add support for
FT_GLYPH_FORMAT_SVG.
* src/sfnt/rules.mk (SFNT_DRV_SRC): Add `ttsvg.c`.
* src/sfnt/sfdriver.c: Include `ttsvg.h`.
(sfnt_interface): Add `tt_face_load_svg`, `tt_face_free_svg` and
`tt_face_load_svg_doc`.
* src/sfnt/sfnt.c: Include `ttsvg.c`.
* src/sfnt/sfobjs.c (sfnt_load_face, sfnt_done_face): Add code to load and
free data of the the SVG table.
* src/sfnt/ttsvg.c: New file, implementing `tt_face_load_svg`,
`tt_face_free_svg` and `tt_face_load_svg_doc`.
* src/sfnt/ttsvg.h: Declarations of the SVG functions in
`ttsvg.c`.
This flag is going to be used to conditionally compile support for OT-SVG
glyphs. FreeType will do the parsing and rely on external hooks for
rendering of OT-SVG glyphs.
* devel/ftoption.h, include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_SVG): New flag.
It might be surprising that FreeType does not have default ppem and
the size has to be set explicitly or face undefined behavior with
undefined variables and errors. This offers an alternative to
missing or zero scale by simply setting FT_LOAD_NO_SCALE. Defined
behavior is bettr than undefined one.
This is alternative to !132 and discussed in
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43708
* src/base/ftobjs.c (FT_Load_Glyph): Deal with zero scale.
* include/freetype/freetype.h: Document it.
In the unlikely case the source is built with OpenWatcom's -ec?
switches to enforce a calling convention, the qsort() compare
function must still be set to __watcall.
* include/freetype/internal/compiler-macros.h (FT_COMPARE_DEF):
Updated.
* include/freetype/config/integer-types.h: Make sure `long long` is
used then available.
* include/freetype/internal/ftcalc.h (FT_MSB): Add Watcom C/C++ pragma.
The `hdmx` table is supposed to be sorted by ppem size, which
enables binary search. We also drop the check for the sufficient
length of the record because it is now enforced when the table
is loaded.
* include/freetype/internal/tttypes.h (TT_FaceRec): Store the `hdmx`
record pointers sorted by ppem instead of ppem's themselves.
* src/truetype/ttpload.c (tt_face_load_hdmx): Prudently sort records.
(tt_face_get_device_metrics): Implement binary search to retrieve
advances.
The `hdmx` matching can be done before the glyph is loaded.
* include/freetype/internal/tttypes.h (TT_LoaderRec): Add a field.
* src/truetype/ttgload.c (compute_glyph_metrics): Relocate the `hdmx`
code from here...
(tt_loader_init): ... to here, before the glyph is loaded.

We really have to use double casts to avoid issues with C's and C++'s
signedness propagation rules in implicit casts.
Reported as
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=41178https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=41182
* include/freetype/config/public-macros.h (FT_STATIC_CAST,
FT_REINTERPRET_CAST): Modify macro to take two arguments.
Update all callers.
(FT_STATIC_BYTE_CAST): New macro.
* include/freetype/freetype.h (FT_ENC_TAG): Use `FT_STATIC_BYTE_CAST`.
* include/freetype/ftimage.h (FT_IMAGE_TAG): Ditto.
* include/freetype/fttypes.h (FT_MAKE_TAG): Ditto.
Use `FT_Tag` for casting.
* src/ftraster/ftmisc.h (FT_MAKE_TAG): Removed, no longer needed.
(FT_STATIC_BYTE_CAST): New macro.
* src/smooth/ftgrays.c (FT_STATIC_CAST): Replace with...
(FT_STATIC_BYTE_CAST): ... this.
Many FreeType clients use C++. However `g++ -Wold-style-cast` warns for
macros with C-style casts even for system header files; this also affects
directories included with `-isystem`. While this could be seen as a problem
with g++, the problem is more a philosophical one: Over the time, C and C++
diverged more and more, and some features of C are no longer the 'right'
solution in C++.
* include/freetype/config/public-macros.h (FT_STATIC_CAST,
FT_REINTERPRET_CAST): New macros.
* include/freetype/freetype.h (FT_ENC_TAG, FT_LOAD_TARGET_,
FT_LOAD_TARGET_MODE): Use `FT_STATIC_CAST`.
Correctly handle negative 'signed char' input.
* include/freetype/ftimage.h (FT_IMAGE_TAG): Ditto.
* include/freetype/fttypes.h (FT_MAKE_TAG, FT_BOOL): Ditto.
* include/freetype/ftmodapi.h (FT_FACE_DRIVER_NAME): Use
`FT_REINTERPRET_CAST`.
* src/smooth/ftgrays.c (FT_STATIC_CAST)[STANDALONE_]: New macro.
[!STANDALONE]: Include `FT_CONFIG_CONFIG_H`.
Fixes#1116.
DLG_STATIC is intended to disable Windows DLL linking attributes.
It does not hurt to define it explicitly when we wrap DLG code.
This fixes tons of LNK4286 and C4273 warnings from MSVC if we
forget to define DLG_STATIC as a compiler option.
* builds/windows/vc2010/freetype.vcxproj: Remove DLG_STATIC option.
* src/dlg/dlgwrap.c [FT_DEBUG_LOGGING]: Define DLG_STATIC.
* include/freetype/internal/ftdebug.h [FT_DEBUG_LOGGING]: Ditto.
FT_QNEW_ARRAY and FT_QRENEW_ARRAY were using the non-Q
FT_MEM_NEW_ARRAY and FT_MEM_RENEW_ARRAY. Change these to use the Q
versions. Also fix the one issue discovered in tt_face_load_name
where table->names is created with FT_QNEW_ARRAY but the extra
string member is not initialized to NULL.
* include/freetype/internal/ftmemory.h (FT_Q(RE)NEW_ARRAY):
Use FT_MEM_Q(RE)NEW_ARRAY as needed.
* src/sfnt/ttload.c (tt_face_load_name): Initialize `entry->string`.
