Commit	Date	Message
205d1ae4	2021-07-12T22:03:25	Small clean-ups for the last few commits. * include/freetype/fttrace.h (afwarp): Removed.
a212668c	2021-06-02T19:07:56	Remove obsolete AF_Angle type and related sources. Move the af_sort_xxx() functions from afangles.c to afhints.c in order to get rid of the obsolete angle-related types, macros and function definitions.
2f11522a	2021-06-02T19:05:09	Remove experimental auto-hinting 'warp' mode. This feature was always experimental, and probably nevery worked properly. This patch completely removes it from the source code, except for a documentation block describing it for historical purpose.
15e88980	2021-06-02T18:54:41	Remove experimental "Latin2" writing system (FT_OPTION_AUTOFIT2) This code has always been experimental and was never compiled anyway (FT_OPTION_AUTOFIT2 does not appear in ftoption.h or even any of our build files).
59e95b01	2021-07-12T06:01:14	Update 'dlg' subproject.
50d0033f	2021-07-05T05:44:13	meson.build: Minor doc fix.
89c60eca	2021-07-05T05:39:59	* src/base/ftlcdfil.c (FT_Library_SetLcdGeometry): Fix argument. Reported by Hin-Tak.
5e32a034	2021-07-03T20:24:16	README.git: Revised.
a399fb89	2021-07-03T16:34:01	meson.build: Minor doc improvements.
4cb8a88a	2021-07-03T10:23:39	* meson_options.txt: Sort alphabetically; no final full stops.
d3dc2da9	2021-06-30T18:22:29	* src/truetype/ttgxvar.c (tt_set_mm_blend): Test `coords`. It is undefined behavior to pass `NULL` to `memcpy`. `coords' is passed to `memcpy` but `TT_Get_MM_Blend` and `TT_Get_Var_Design` explictly call `tt_set_mm_blend` with `coords` as `NULL`. In addition, `TT_Set_MM_Blend` has a similar possible issue.
286da6c5	2021-06-22T15:01:19	[sfnt] Support PaintScale in 'COLR' v1 parsing. * include/freetype/ftcolor.h (FT_PaintFormat): Renumber values, add `FT_COLR_PAINTFORMAT_SCALE`. (FT_PaintScale): New structure to represent 'PaintScale' tables. (FT_COLR_Paint): Updated. src/sfnt/ttcolr.c (FT_PaintFormat_Internal): New enumeration. (read_paint): Parse 'PaintScale' and friends.
0348c627	2021-06-29T20:51:32	[sfnt] Handle fonts without layer list in 'COLR' v1. 'COLR' v1 fonts do not necessarily need to have a layer list; for this reason, 'fontTools' recently started generating fonts in a way that drops the layer list if there are no layers in it. This results in the layer list offset becoming zero, which FreeType treated as an invalid table. Fix that and handle the case for layer list offset being 0. This slightly changes how we need to calculate the starting offset for paints. * src/sfnt/ttcolr.c (tt_face_load_colr): Handle case of layer list offset being zero without outright rejecting table.
f27b4834	2021-06-30T10:54:59	* src/raster/ftraster.c (Render_Single_Pass): Simplify `band_stack'.
90ecac41	2021-06-30T10:23:42	Update `CHANGES` file; other minor doc fixes.
69c3516c	2021-06-29T23:51:23	[raster] Do not skip the second pass without dropout control. The second pass also fixes horizontal lines through the pixel centers. * src/raster/ftraster.c (black_TWorker): Do not use `second_pass'. (Render_Glyph): Skip the second pass only with the appropriate flag.
3696ac5a	2021-06-29T23:27:10	[raster] Handle sub-band stack locally. * src/raster/ftraster.c (black_TWorker): Move `band_stack' from here.. (Render_Single_Pass): ... to here and accept limit arguments. (Render_Glyph): Updated.
7be47010	2021-05-18T10:33:25	[CI] Introduce linux CI and refactor job names * .gitlab-ci.yml: Added jobs for building freetype on linux.
e1b1b542	2021-06-29T06:07:00	ftcolor.h: Minor grammar fix.
c852388d	2021-06-28T23:26:10	[raster] Handle Bézier stack locally. * src/raster/ftraster.c (black_TWorker): Move `arcs' from here... (Conic_To, Cubic_To): ... to here to tighten their scope. (Bezier_Up, Bezier_Down): ... Take the current `arc' argument.
7d4e55c3	2021-06-28T16:29:49	[sfnt] Improve paint limit checks Paint tables can appear before the `base_glyphs_v1` offset if the font is produced with the layer list before the base glyph list. In this case paint tables can occur after the layer list but before the base glyph list. Checks in the 'COLR' v1 code were rejecting fonts with this layout. Improve these checks by calculating a minimum offset after which paint tables can occur and use that in safety checks. * src/sfnt/ttcolr.c (Colr, tt_face_load_colr): Declare `paint_start_v1` and calculate that as the minimum of the end of layer list and base glyph list. (get_child_table_pointer, read_paint, tt_face_get_paint_layers): Use that in safety checks.
3a278381	2021-06-28T10:22:03	[raster] Clean up vertical sweep. * src/raster/ftraster.c (black_TWorker): Replace the current line offset with the pointer and drop the increment. (Function_Sweep_Init): Take values as arguments instead of pointers. (Vertical_Sweep_*, Horizontal_Sweep_Init, Draw_Sweep): Updated.
fb4511eb	2021-06-26T08:49:20	[raster] Make `band_top' local variable. * src/raster/ftraster.c (black_TWorker): Move `band_top' from here... (Render_Single_Pass): ... to here, and refactor. (Render_Glyph): Updated.
f6370e2f	2021-06-25T22:59:39	[raster] Adjust sub-band bisecting limits. We can bisect a band until it is just a single scan line. This might be slow and cause time-outs but if we need to impose limits it should be elsewhere. * src/raster/ftraster.c (Render_Single_Pass): Tweak sub-banding.
bc1029b9	2021-06-25T18:20:57	* src/raster/ftraster.c (Render_Single_Pass): Remove dead code.
ff407765	2021-06-25T09:19:51	[base] Add trace level to logging output. Some practical debugging work has shown that displaying level X of an `FT_TRACEX` macro in the output of `FT2_DEBUG="... -v"` would be very helpful to find out which trace level should be selected. As an example, we now get output like ``` [ttobjs:2] TTF driver [ttobjs:2] SFNT driver [sfobjs:2] not a font using the SFNT container format [t1objs:2] Type 1 driver [stream:7] FT_Stream_EnterFrame: 14 bytes ``` * include/freetype/internal/ftdebug.h (FT_LOGGING_TAGX): New macro. (FT_LOG): Use it to add the trace level to the logging tag. * include/freetype/internal/fttrace.h (FT_MAX_TRACE_LEVEL_LENGTH): Adjust. * docs/DEBUG: Updated.
1e0cef9e	2021-06-24T00:19:50	[smooth, raster] Fix up and align error codes. FT_Render_Glyph picked up FAILURE or 1 returned from the raster function, which became a confusing error code. Instead, return Raster_Overflow in the unlikely event that banding does not help or another meaningful error. * src/smooth/ftgrays.c (gray_convert_glyph_inner, gray_convert_glyph): Use Raster_Overflow when the rendering pool is exhausted and return it if banding does not help. (gray_raster_render): Use Smooth_Err_Ok. * src/raster/ftraster.c (Render_Single_Pass): Return Raster_Overflow if banding does not help or another error code.
d8ac180c	2021-06-23T23:32:02	[smooth, raster] Remove synonymous error macros. * src/smooth/ftgays.c [STANDALONE_]: s/ErrRaster_/Smooth_Err_/. (gray_convert_glyph_inner): Updated accordingly. * src/raster/ftraster.c [STANDALONE_]: Do not abbreviate error macros. (New_Profile, End_Profile, Insert_Y_Turn, Line_Up, Bezier_Up, Decompose_Curve, Draw_Sweep, Render_Single_Pass, ft_black_render): Updated accordingly.
1e65e605	2021-06-23T08:14:42	fterrors.h: Fix documentation extraction of `FT_Error_String`.
4cb21b9a	2021-06-22T20:50:48	[sfnt] s/PaintTransformed/PaintTransform/, s/transformed/transform/. * include/freetype/ftcolor.h (FT_PaintTransformed, FT_PaintFormat, FT_COLR_Paint): Do it to make it harmonize with other names such as 'PaintTranslate'. * src/sfnt/ttcolr.c (read_paint, tt_face_get_paint): Ditto.
284eec1e	2021-06-22T14:21:49	Move 'COLR' API to `ftcolor.h`. * include/freetype/freetype.h: Cut section layer managament containing 'COLR' v0 and v1 API and move it to `ftcolor.h` as requested by Werner on freetype-devel. * include/freetype/ftcolor.h: Paste that section.
bcd73f7d	2021-06-20T16:23:40	freetype.h: Mark 'COLR' v1 API as experimental.
008e42a1	2021-06-19T15:45:46	ftver.rc: Update copyright year.
b460a506	2021-06-19T07:03:40	[truetype] Fix integer overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=35312 * src/truetype/ttinterp.c (Ins_JMPR): Use `ADD_LONG`.
232243e7	2021-06-19T06:32:29	Prevent hinting if there are too many segments. This speeds up handling of broken glyphs. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=35309 * src/autofit/aflatin.c (af_latin_hints_compute_segments): Implement it.
61bac759	2021-06-18T17:38:00	* src/sdf/ftsdfrend.c (ft_(b)sdf_render): Do not FT_ERROR routinely.

8336d53c	2021-06-12T22:33:08	[type42] Fix new memory leak. We need to inverse inheritance of FT_GlyphSlot_Internal so that we have a chance to free the rendered bitmap from the parent slot. * src/type42/t42objs.c (T42_GlyphSlot_Init): Remove the internal parts of the child `ttslot' and replace it with the parent structure. (T42_GlyphSlot_Done): Updated accordingly.
db0f2c44	2021-06-12T10:05:07	[psaux] Fix another assertion. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escCALLOTHERSUBR>: Convert assertion into error, since the problem can happen with invalid user input. Test case is file fuzzing/corpora/legacy/oss-fuzz/5754332360212480-unknown-read in the `freetype2-testing` repository.
a34afe67	2021-06-12T08:40:16	[psaux] Fix assertions. * src/psaux/pshints.c (cf2_hintmap_adjustHints): Check for overflow before emitting an assertion error.

640f654b	2021-06-08T16:45:04	Fix 'devel' build for COLR 'v1'. * devel/ftoption.h: Synchronize with `include/freetype/config/ftoption.h`.
b24cfc8d	2021-06-08T15:26:41	[sfnt] Sanitize cmap4 table better. Fixes #1062. * src/sfnt/ttcmap.c (tt_cmap4_validate): Handle a too-small value of `length` gracefully.
ee6d03d3	2021-06-08T14:29:11	[sfnt] Pointer validity check when reading COLR 'v1' layers * src/sfnt/ttcolr.c (tt_face_get_paint_layers): In addition to the existing sanity checks, ensure that the pointer to the layer to be read is within the 'COLR' v1 table.
41fa19fc	2021-06-08T10:32:20	* src/sdf/ftsdfcommon.c: Fix inclusion of header files.
35b21c71	2021-06-08T09:06:39	[sdf] Make `make multi` work. * src/sdf/ftsdf.c: Include `ftbitmap.h`. * src/sdf/ftsdfcommon.h: Move function bodies to `ftsdfcommon.c`. Include `ftobjs.h` to get definitions of `FT_LOCAL` and friends. * src/sdf/ftsdfcommon.c: New file. * src/sdf/rules.mk, src/sdf/sdf.c: Updated.
36ee7171	2021-06-08T09:00:39	[sdf] Formatting and improved comments.
2b1d5562	2021-06-08T08:29:34	[sdf] Use 8 bits for final SDF output instead of 16bits. Since 8-bits is enough to represent SDF data we no longer require 16-bits for this purpose. Also, we now normalize the output data to use the entire 8-bit range efficiently. For example: if we use 3.5 format with a spread of 1 we basically only use the starting 5-bits. By normalizing we can use the entire 8-bit range. * include/freetype/freetype.h (FT_Render_Mode): Updated description for `FT_RENDER_MODE_SDF` regarding this change. * include/freetype/ftimage.h (FT_Pixel_Mode): Removed `FT_PIXEL_MODE_GRAY16` since no longer required. * include/freetype/fttypes.h (FT_F6Dot10): Removed since no longer required. * src/sdf/ftsdfrend.c (ft_sdf_render, ft_bsdf_render): Allocate 8-bit bitmap instead of 16-bit buffer. * src/sdf/ftsdfcommon.h (map_fixed_to_sdf): Added function to convert 16.16 distance value to our desired format. * src/sdf/ftsdf.c (sdf_generate_with_overlaps, sdf_generate_bounding_box): Use the new `map_fixed_to_sdf` function and also use 8-bit output buffer. * src/sdf/ftbsdf.c (finalize_sdf): Output to a 8-bit buffer instead of 16-bit buffer.
2a6665a4	2021-06-01T15:25:31	[sfnt] Fix fallout from 2021-05-29 change. * src/sfnt/ttcolr.c (find_base_glyph_record, find_base_glyph_v1_record): Adjust binary search. Needs to be updated with change to unsigned.
7ca7da9d	2021-06-02T06:59:01	* src/autofit/aflatin.c (af_latin_metrics_scale_dim): Fix tracing. Problem reported by Alexei.
0abbc9f5	2021-06-02T06:36:11	[psaux] Fix MSVC compiler warnings. * src/psaux/afmparse.c (afm_parse_track_kern, afm_parse_kern_pairs): Add cast.

a50c39aa	2021-05-29T09:50:29	Fix compilation errors and (some) warnings for clang++. * src/autofit/afmodule.c (AF_GlyphHintsRec): Make it static. * src/cache/ftcache.c (FTC_Cache_NewNode), src/cache/ftcsbits.c (ftc_snode_compare): Remove semicolon. * src/cff/cffparse.c (cff_parser_run): Add `break` statement. * src/cid/cidload.c (cid_hex_to_binary): Add cast. * src/sdf/ftbsdf.c (CHECK_NEIGHBOR): Use `do {} while(0)` loop. (bsdf_init_distance_map, finalize_sdf, bsdf_raster_render): Add casts. * src/sdf/ftsdf.c (sdf_generate_bounding_box, sdf_generate_with_overlaps): Ditto. * src/sdf/ftsdfcommon.h (square_root): Ditto. * src/sdf/ftsdfrend.c (sdf_property_get, ft_sdf_render, ft_bsdf_render): Ditto. * src/sfnt/ttcolr.c (find_base_glyph_record, find_base_glyph_v1_record): Fix variable signedness. (read_color_line): Add cast. (read_paint): Add casts. Fix signedness issue. (tt_face_get_colorline_stops) Fix signedness issues. * src/sfnt/ttpost.c (load_format_20): Add casts. * src/truetype/ttsubpix.c (TWEAK_RULES, TWEAK_RULES_EXCEPTIONS): Remove final semicolons.
2bfdc161	2021-05-29T00:27:40	[build] Allow overriding of `ANSIFLAGS` for GNU make build. * builds/*: Implement it.
28eee363	2021-05-27T11:38:56	[type42] Fix auto-hinting. The autohinter could not access the base (unscaled) outline in the child TrueType glyph slot. We now share the internal parts between the parent and child glyph slots. Fixes #1057. * src/type42/t42objs.c (T42_GlyphSlot_Init): Remove the internal parts of `T42_GlyphSlot' and replace it with the child TrueType structure. (T42_GlyphSlot_Done): Updated accordingly.
0d1c306e	2021-05-25T11:27:56	[psaux] Guard and trace AFM kern data allocation. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=31543 * include/freetype/internal/fttrace.h: Add 'afmparse' trace component. * src/psaux/afmparse.c (FT_COMPONENT): Define. (afm_parse_track_kern, afm_parse_kern_pairs): Protect against allocations bombs. Add tracing. (afm_parse_kern_data): Don't allow multiple kern data sections.
5f485339	2021-05-24T08:24:36	.gitignore: Add `subprojects` directory, fix some patterns.
16947c0e	2021-05-23T05:36:16	* meson.build (ft2_public_headers): Add missing `ftcid.h'. Fixes #1058.
2468e59a	2021-05-20T22:20:36	[type42] Avoid some memory zeroing. * src/type42/t42objs.c (T42_Open_Face): Tweak allocation macro. * src/type42/t42parse.c (t42_parse_sfnts): Ditto.
ebf9e5ac	2021-05-15T22:36:00	[CMake] Update dependency finders. 1. Fixes CMake using any found HarfBuzz version lower than the minimum required. This is based on HALX99's merge request at https://gitlab.freedesktop.org/freetype/freetype/-/merge_requests/31 2. Update FindHarfBuzz.cmake from https://github.com/WebKit/WebKit/blob/1ce32454/Source/cmake/FindHarfBuzz.cmake and guard post-CMake-3.1 features to keep the minimum version unchanged 3. Update FindBrotliDec.cmake to stop the warnings, based on what https://github.com/google/woff2/blob/a0d0ed7d/cmake/FindBrotliDec.cmake is doing * CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Implement 1 and 2. * builds/cmake/FindBrotliDec.cmake: Implement 3.
06e21ffe	2021-05-18T14:49:50	[gzip] Use exact type for `ft_gzip_alloc` and `ft_gzip_free`. While a function pointer may be cast to another function pointer type, it is required to cast the function pointer back to the original function pointer type before calling it. If a parameter is a pointer the exact pointer type is required. Using a pointer to a different underlying type is technically undefined behavior. The wrapper functions `ft_gzip_alloc` and `ft_gzip_free` took `FT_Memory` (a `FT_MemoryRec_`) instead of `voidpf` (`void`), so when gzip calls these callbacks through `alloc_func` or `free_func` it invokes undefined behavior. On most platforms this works out as expected, but newer undefined behavior detectors and targets like wasm can detect this and will produce an error. * src/gzip/ftgzip.c (ft_gzip_alloc, ft_gzip_free): Update signatures to exactly match `alloc_func` and `free_func`, respectively. Internally, cast the `void*` opaque pointer to `FT_Memory`.
81852fbc	2021-05-18T22:18:17	Prioritize the anti-aliasing renderer module. * modules.cfg: Reorder the renderers. * include/freetype/config/ftmodule.h: Ditto.
1bc801b0	2021-05-16T23:12:01	[sfnt] Additional guards on the POST table. Fixes timeout (#1055) analyzed by Ben Wagner, reported as https://crbug.com/1194092 * src/sfnt/ttload.c (tt_face_load_post): Check POST format. * src/sfnt/sfobjs.c (sfnt_load_face): Synthesize the missing unicode charmap only if the glyph names exist. * src/psnames/psmodule.c (ps_unicode_value): Short cut ".notdef" and ".null".
de151657	2021-05-13T23:08:31	[psaux] Use doubling allocation strategy for CF2_ArrStack. Fixes timeout reported as https://crbug.com/1206181 * src/psaux/psarrst.c (cf2_arrstack_{push,init}): Implement it. * src/psaux/psarrst.h (CF2_ArrStackiRec): Drop `chunk'.
2d3f5dd2	2021-05-12T17:24:35	* src/smooth/ftgrays.c (FT_MAX_GRAY_SPANS): Increase from 10 to 16. Ten was barely enough for two slanted stems. Sixteen can actually fit a bit more complicated scanlines.
c653b8d2	2021-05-12T16:17:21	* src/smooth/ftgrays.c (FT_GRAY_SET): Adjust for better code.
8f43d324	2021-05-12T00:04:59	[smooth] Faster bitmap sweeping. Selecting the fill rule or checking the direct mode each time we call `gray_hline' is sub-optimal. This effectively splits the direct mode into a separate code path while inlining `gray_hline' and saving 5-7% of rendering time. * src/smooth/ftgrays.c (gray_hline): Eliminated in favor of... (FT_FILL_RULE, FT_GRAY_SET): ... these new macros... (gray_sweep): ... inlined here. (gray_sweep_direct): New function that handles the direct span buffer. (gray_TWorker): Remove the span buffer. (gray_raster_render, gray_convert_glyph): Updated.
b0702645	2021-05-10T22:06:01	* src/smooth/ftgrays.c (gray_hline): Simplify even-odd computations. It is too bad the even-odd rule is not used much.
967a34ee	2021-05-07T19:17:48	[type1] Avoid MM memory zeroing. * src/type1/t1load.c (t1_allocate_blend, parse_blend_design_map): Tweak allocation macros. * src/type1/t1objs.c (T1_Face_Done): Minor.
2f62d8e0	2021-05-07T09:33:41	* src/bdf/bdflib.c (_bdf_list_ensure): Tweak allocation macro.
79ed536d	2021-05-06T23:46:46	* src/psaux/psobjs.c (ps_parser_load_field): Tweak allocation macro.
44c59414	2021-05-06T22:54:03	* src/sfnt/sfobjs.c (sfnt_load_face): Tweak allocation macro.
998c7c0f	2021-05-06T22:51:37	* src/cid/cidload.c (cid_read_subrs): Tweak allocation macro.
2d957848	2021-05-06T22:49:13	* src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Tweak allocation.
8150ed0d	2021-05-05T23:30:46	[cff,psaux] Avoid memory zeroing (contd.). * src/cff/cffload.c (cff_blend_doBlend, cff_blend_build_vector): Tweak allocation macros. * src/psaux/psarrst.c (cf2_arrstack_setNumElements): Ditto. * src/psaux/psstack.c (cf2_stack_init): Ditto.
82fd32d6	2021-05-03T13:49:14	* src/cid/cidload.c (cid_hex_to_binary): Improve return value. Add argument to return the actual number of bytes that were decoded. The actual number of bytes decoded can be quite variable depending on the number of ignored 'whitespace' bytes or early termination with `>`. (cid_face_open): Updated to use this calculated value.

* src/truetype/ttgxvar.c (tt_set_mm_blend): Test `coords`. It is undefined behavior to pass `NULL` to `memcpy`. `coords' is passed to `memcpy` but `TT_Get_MM_Blend` and `TT_Get_Var_Design` explictly call `tt_set_mm_blend` with `coords` as `NULL`. In addition, `TT_Set_MM_Blend` has a similar possible issue.

[sfnt] Handle fonts without layer list in 'COLR' v1. 'COLR' v1 fonts do not necessarily need to have a layer list; for this reason, 'fontTools' recently started generating fonts in a way that drops the layer list if there are no layers in it. This results in the layer list offset becoming zero, which FreeType treated as an invalid table. Fix that and handle the case for layer list offset being 0. This slightly changes how we need to calculate the starting offset for paints. * src/sfnt/ttcolr.c (tt_face_load_colr): Handle case of layer list offset being zero without outright rejecting table.

2021-06-28T16:29:49

[sfnt] Improve paint limit checks Paint tables can appear before the `base_glyphs_v1` offset if the font is produced with the layer list before the base glyph list. In this case paint tables can occur after the layer list but before the base glyph list. Checks in the 'COLR' v1 code were rejecting fonts with this layout. Improve these checks by calculating a minimum offset after which paint tables can occur and use that in safety checks. * src/sfnt/ttcolr.c (Colr, tt_face_load_colr): Declare `paint_start_v1` and calculate that as the minimum of the end of layer list and base glyph list. (get_child_table_pointer, read_paint, tt_face_get_paint_layers): Use that in safety checks.

[base] Add trace level to logging output. Some practical debugging work has shown that displaying level X of an `FT_TRACEX` macro in the output of `FT2_DEBUG="... -v"` would be very helpful to find out which trace level should be selected. As an example, we now get output like ``` [ttobjs:2] TTF driver [ttobjs:2] SFNT driver [sfobjs:2] not a font using the SFNT container format [t1objs:2] Type 1 driver [stream:7] FT_Stream_EnterFrame: 14 bytes ``` * include/freetype/internal/ftdebug.h (FT_LOGGING_TAGX): New macro. (FT_LOG): Use it to add the trace level to the logging tag. * include/freetype/internal/fttrace.h (FT_MAX_TRACE_LEVEL_LENGTH): Adjust. * docs/DEBUG: Updated.

2021-06-08T08:29:34

[sdf] Use 8 bits for final SDF output instead of 16bits. Since 8-bits is enough to represent SDF data we no longer require 16-bits for this purpose. Also, we now normalize the output data to use the entire 8-bit range efficiently. For example: if we use 3.5 format with a spread of 1 we basically only use the starting 5-bits. By normalizing we can use the entire 8-bit range. * include/freetype/freetype.h (FT_Render_Mode): Updated description for `FT_RENDER_MODE_SDF` regarding this change. * include/freetype/ftimage.h (FT_Pixel_Mode): Removed `FT_PIXEL_MODE_GRAY16` since no longer required. * include/freetype/fttypes.h (FT_F6Dot10): Removed since no longer required. * src/sdf/ftsdfrend.c (ft_sdf_render, ft_bsdf_render): Allocate 8-bit bitmap instead of 16-bit buffer. * src/sdf/ftsdfcommon.h (map_fixed_to_sdf): Added function to convert 16.16 distance value to our desired format. * src/sdf/ftsdf.c (sdf_generate_with_overlaps, sdf_generate_bounding_box): Use the new `map_fixed_to_sdf` function and also use 8-bit output buffer. * src/sdf/ftbsdf.c (finalize_sdf): Output to a 8-bit buffer instead of 16-bit buffer.

[gzip] Use exact type for `ft_gzip_alloc` and `ft_gzip_free`. While a function pointer may be cast to another function pointer type, it is required to cast the function pointer back to the original function pointer type before calling it. If a parameter is a pointer the exact pointer type is required. Using a pointer to a different underlying type is technically undefined behavior. The wrapper functions `ft_gzip_alloc` and `ft_gzip_free` took `FT_Memory` (a `FT_MemoryRec_*`) instead of `voidpf` (`void*`), so when gzip calls these callbacks through `alloc_func` or `free_func` it invokes undefined behavior. On most platforms this works out as expected, but newer undefined behavior detectors and targets like wasm can detect this and will produce an error. * src/gzip/ftgzip.c (ft_gzip_alloc, ft_gzip_free): Update signatures to exactly match `alloc_func` and `free_func`, respectively. Internally, cast the `void*` opaque pointer to `FT_Memory`.

[smooth] Faster bitmap sweeping. Selecting the fill rule or checking the direct mode each time we call `gray_hline' is sub-optimal. This effectively splits the direct mode into a separate code path while inlining `gray_hline' and saving 5-7% of rendering time. * src/smooth/ftgrays.c (gray_hline): Eliminated in favor of... (FT_FILL_RULE, FT_GRAY_SET): ... these new macros... (gray_sweep): ... inlined here. (gray_sweep_direct): New function that handles the direct span buffer. (gray_TWorker): Remove the span buffer. (gray_raster_render, gray_convert_glyph): Updated.

The actual number of bytes decoded can be quite variable depending on the number of ignored 'whitespace' bytes or early termination with `>`. (cid_face_open): Updated to use this calculated value. This avoids trusting `parser->binary_length` is always be correct and reading uninitialized bits if fewer are actually decoded. First reported as https://crbug.com/1203240
