16586859 2020-06-13 21:15:45 Remove redundant inclusion of `ft2build.h'. * */*: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'.
e1339133 2020-06-08 13:31:55 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.
4eee1340 2020-05-18 09:16:12 Remove Jamfile files from the tree. These have not been used in a very, very long time, so better remove them. A corresponding patch will be submitted to the `freetype2-demos' repository. * src/Jamfile, src/*/Jamfile, Jamrules: Delete.
a45da253 2020-05-08 10:59:37 * src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#58319). The font that exceeds the old limit is Icono Regular, version 1.00000.
11975fe9 2020-02-29 20:18:00 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.
216e0776 2020-02-28 07:43:00 [truetype] Add better checks for loading `gvar' table (#57905). * src/truetype/ttgxvar.c (ft_var_load_gvar): Delay settings of any `blend->xxxcount' values until the corresponding data has been checked. Also do some sanitizing to avoid a too early exit. (TT_Vary_Apply_Glyph_Deltas): Improve tracing message.
4a19a53d 2020-02-04 13:37:19 * src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#57732). The font that exceeds the old limit is Constantine, version 1.001.

10d8de75 2019-12-30 11:22:04 [truetype] Fix UBSan warning on offset to nullptr (#57501). * src/truetype/ttinterp.c (Ins_CALL): Fail if `exc->FDefs' is null.
8cee1dde 2019-12-17 14:12:38 Fix more UBSan warnings on adding offset to nullptr (#57432). * src/truetype/ttinterp.c (Ins_LOOPCALL), src/psaux/psft.c (cf2_initLocalRegionBuffer): Use `FT_OFFSET'.
7e1b39f6 2019-12-16 11:07:58 [truetype] Fix UBSan warnings on adding offsets to nullptr. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1032152 * src/truetype/ttinterp.c (Ins_FDEF, Ins_IDEF): Use `FT_OFFSET'.

dfc9a049 2019-12-05 08:44:30 * src/truetype/ttinterp.c (TT_RunIns): Use `FT_OFFSET'. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1030614
551bd3a9 2019-12-03 11:52:48 More nullptr offset UBSan warnings (#57331, #57347). * src/autofit/afcjk.c (af_cjk_hints_compute_segments), src/psaux/psft.c (cf2_getSeacComponent), src/truetype/ttinterp.c (Ins_UNKNOWN): Use `FT_OFFSET'.
9df460b6 2019-11-23 11:09:40 [truetype] Avoid sanitizer warning (#57289). * src/truetype/ttpload.c (tt_face_get_device_metrics): Use `FT_OFFSET'.
c67b9a1c 2019-11-23 11:01:18 [truetype] Fix integer overflow (#57287). * src/truetype/ttgload.c (compute_glyph_metrics): Use `SUB_LONG'.
59415658 2019-08-27 14:07:14 [truetype] Prevent crash in `TT_Set_Named_Instance' (#56813). * src/truetype/ttgxvar.c (TT_Set_Named_Instance): Fix error handling.
7d1d3b9a 2019-08-26 09:08:56 [type1] Fix `FT_Get_Var_Axis_Flags' (#56804). * src/type1/t1load.c (T1_Get_MM_Var): Allocate space for axis flags. Also remove redundant assignment.
12e4307d 2019-07-12 10:48:10 Properly handle phantom points for variation fonts (#56601). * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Scale phantom points if HVAR and/or VVAR is present.
d1b16325 2019-06-11 21:43:47 * src/truetype/ttobjs.c (tt_check_trickyness_family): Add `const'.
f37083ed 2019-05-29 08:15:38 [truetype] Fix copy-and-paste error (#56409). * src/truetype/ttgload.c (load_truetype_glyph): Use correct indices into `unrounded' array for phantom points.
49079ce2 2019-05-29 08:08:53 [truetype] Fix 32bit builds (#56404). Patch suggested by Ben Wagner <bungeman@google.com>. * src/truetype/ttgxvar.c (FT_fixedToInt, FT_fixedToFdot6): Remove harmful cast to unsigned type.
86d997e5 2019-05-26 09:37:41 * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Improve accuracy.
306d2f6c 2019-05-23 14:41:57 [truetype] Draw glyphs without deltas in variation font (#56374). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Always fill `unrounded' array.
c3be6f06 2019-05-21 11:23:36 src/truetype/ttinterp.c: Give order of operations for some instructions.
262fce44 2019-05-21 09:58:51 * src/truetype/ttinterp.c (opcode_name): Improve mnemonics.
8eafa528 2019-05-21 09:57:38 ttinterp.c: Improve documentation of engine compensation.
b0522701 2019-05-16 12:52:57 [truetype] Actually scale varied CVT values. Up to now, only the unscaled CVT values were varied; in other words, the `CVAR' data was never used for bytecode hinting. * src/truetype/ttgxvar.c (tt_cvt_ready_iterator): New auxiliary function. (tt_face_vary_cvt): Use it to trigger rescaling of CVT values.
37580053 2019-05-16 12:15:54 [truetype] Use 26.6 format for storing unscaled CVT values. If `CVAR' data is applied to variation fonts, fractional values are possible. * include/freetype/internal/tttypes.h (TT_FaceRec): Change type of `cvt' from `FT_Short' to `FT_Int32'. * src/truetype/ttgxvar.c (FT_fdot6ToFixed): New macro. (tt_face_vary_cvt): Use it to update code to 26.6 format. * src/truetype/ttobjs.c (tt_size_run_prep): Update code to 26.6 format. * src/truetype/ttpload.c (tt_face_load_cvt): Stora data in 26.6 format.
ac335cd5 2019-05-16 10:15:53 * src/truetype/ttgload.c (load_truetype_glyph): Init `unrounded'. This fixes linear advance width values for spacing glyphs. Bug introduced 2019-05-09.
535b687e 2019-05-16 09:55:16 [truetype] Avoid code duplication. * src/truetype/ttobjs.c (tt_size_run_prep): Scale CVT values in this function. (tt_size_ready_bytecode): Updated. * src/truetype/ttgload.c (tt_loader_init): Updated.
94ebc248 2019-05-12 21:05:36 [truetype] Doh. Fix last commit to make it work. Very embarassing :-) Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14701 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14705 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14710 * src/truetype/ttgload.c (IS_DEFAULT_INSTANCE): Move up and add argument; update all callers. (TT_Process_Simple_Glyph): Use it. The `unrounded' array is active for variation fonts only, thus also enclose related code with `#ifdef TT_CONFIG_OPTION_GX_VAR_SUPPORT ... #endif' where necessary. Revert commit a113e5d from 2019-05-09, and don't use `extra_points2' but allocate a temporary array. Speed up the scaling of the `unrounded' array. * src/truetype/ttgxvar.c (FT_fixedToInt, FT_FixedToFdot6): Fix type conversions and rounding. The unsigned type must have more or equal bits to the signed type.
1178227b 2019-05-11 09:29:19 [truetype] Increase precision of font variation (#54371). This patch make FreeType use font units in 26.6 format internally instead of integers. * src/truetype/ttgxvar.c (FT_fixedToFdot6): New macro. (TT_Vary_Apply_Glyph_Deltas): Add argument to output unrounded font coordinates. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Use `extra_points2' array to temporarily hold unrounded point coordinates; use them to compute scaled coordinates and linear advance width and height. (load_truetype_code): Adjust similarly.
a113e5df 2019-05-09 11:37:58 * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Minor.
dc39f76c 2019-05-07 10:09:55 * src/truetype/ttgxvar.c: More use of `FT_fdot14ToFixed'.
7b841047 2019-05-04 08:13:22 Various clang 8.0 static analyzer fixes. Reported by Sender Ghost <lightside@gmx.com>. * src/autofit/afcjk.c (af_cjk_hints_compute_edges): Catch a corner case where `edge->first' could be NULL. * src/pfr/pfrobjs.c (pfr_slot_load): Remove unnecessary test of `size'. * src/raster/ftraster.c (Draw_Sweep): Catch a corner case where `draw_right' might be NULL. * src/sfnt/ttmtx.c (tt_face_get_metrics): Fix limit test for `aadvance'. Ensure `abearing' always hold a meaningful result. * src/truetype/ttgload.c (load_truetype_glyph): Ensure `subglyph' is not NULL before accessing it. * src/truetype/ttgxvar.c (TT_Set_Named_Instance): Remove unnecessary test of `namedstyle'. * src/type42/t42parse.c (t42_parser_done): Ensure `parser->root.funcs.done' is not NULL before accessing it.
af400438 2019-04-22 07:41:35 Fix return value of `FT_Set_Named_Instance' (#56186). * src/truetype/ttgxvar.c (TT_Set_Named_Instance): Correctly handle internal return value -1 of `TT_Set_Var_Design'.
75859970 2019-02-23 10:07:09 Update all copyright notices.
b77826e1 2019-02-21 10:23:15 Triage 8ea854bfe92443706d55656072f891ec8f2cb3c2.
8ea854bf 2019-02-21 10:14:57 [truetype] Mask numeric overflows. * src/truetype/ttinterp.c (Move_CVT, Move_CVT_Stretched, Ins_MIRP): Mask numeric overflows. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11681 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11734
b66d6a91 2019-02-06 07:38:25 CHANGES: Document recent metrics change from Nikolaus.
a6feefdf 2019-02-02 15:50:57 [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.
f686ad46 2019-01-22 20:31:44 Update copyright years.
afa043de 2018-12-25 22:44:05 Fix links (mostly http -> https).
2b4e61e4 2018-12-12 09:36:39 Minor documentation fixes.
3e8a2283 2018-12-11 23:54:17 * src/truetype/ttgload.c (TT_Hint_Glyph): Remove useless test. `control_len' only gets its value from `n_ins' (and vice versa), which is always read as `unsigned short' and thus can't be larger than 0xFFFF.
78a1e695 2018-11-27 22:24:06 [type1,cff] Add FT_{Set,Get}_MM_WeightVector API calls. For multiple master fonts, common usage (in Postscript) is to modify the WeightVector of an existing font instance, this addition supports that use. * include/freetype/ftmm.h, src/base/ftmm.c (FT_Set_MM_WeightVector, FT_Get_MM_WeightVector): New API functions. * include/freetype/internalservices/svmm.h (FT_Set_MM_WeightVector_Func, FT_Get_MM_WeightVector_Func): New function types. (MultiMasters): Add `set_mm_weightvector' and `get_mm_weightvector' members. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. * src/cffcffdrivr.c (cff_set_mm_weightvector, cff_get_mm_weightvector): New functions. (cff_service_multi_masters): Register them. * src/truetype/ttdriver.c (tt_service_gx_multi_masters): Updated. This driver doesn't use the new interface. * src/type1/t1load.c (T1_Set_MM_WeightVector, T1_Get_MM_WeightVector): New functions. * src/type1/t1driver.c (t1_service_multi_masters): Register them. * src/type1/t1load.h: Updated.
74cdd75f 2018-11-27 17:55:40 [truetype] Fix numeric overflow (#55103). * src/truetype/ttgload.c (compute_glyph_metrics): Use `SUB_LONG'.
fb0d66d0 2018-11-07 00:47:44 [truetype] Fix VF check from 2018-09-12 (#54973). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Use correct offsets for estimates.
cc288e38 2018-11-04 22:09:16 Minor.
1f43affc 2018-11-04 13:11:16 * src/truetype/ttgxvar.c: Use enum definitions.
d95a12b8 2018-11-03 23:02:58 * src/truetype/ttgxvar.c (ft_var_apply_tuple): Adjust condition.
547f82f2 2018-11-03 23:00:36 * src/truetype/ttgxvar.c (ft_var_apply_tuple): Tracing tweaks.
ce3feb0b 2018-11-03 22:43:21 Revert due to specs: [truetype] Speed up variation IUP. This reverts commit 1e4496c54c010843c1bac56e5d344115d1a49620.
dfa86d65 2018-11-03 22:36:52 Revert "[truetype] Speed up variation IUP." This reverts commit 1e4496c54c010843c1bac56e5d344115d1a49620.
61d50756 2018-11-02 20:42:25 * src/truetype/ttgxvar.c (ft_var_get_item_delta): Fixed logic. Reported and tested by Behdad.
1e4496c5 2018-10-31 23:17:33 [truetype] Speed up variation IUP. * src/truetype/ttgxvar.c (tt_delta_interpolate): Separate trivial snapping to the same position from true interpolation.
300da33d 2018-10-31 21:55:40 * src/truetype/ttgxvar.c (ft_var_get_item_delta): Optimized.
f262d15d 2018-10-07 07:40:37 Minor comment improvement.
a9af6914 2018-09-25 09:10:09 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.
10e54d04 2018-09-13 21:47:35 [truetype] Some fixes for VF checks. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10317 * src/truetype/ttgxvar.c (ft_var_load_gvar): Properly exit memory frame if we have invalid glyph variation data offsets. (tt_face_vary_cvt): Protect against missing `tuplecoords' array. Fix typo.
65681e6d 2018-09-12 07:40:49 [truetype] Improve VF check. Triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10255 * src/truetype/ttgxvar.c (ft_var_load_gvar): Use better limit check for `tupleCount'.
53c5e4bd 2018-09-12 07:27:30 * src/truetype/ttgxvar.c (ft_var_load_gvar): Check `glyphoffsets'.
1c04eed7 2018-09-07 06:40:55 [truetype] Fix assertion failure. Triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10212 * src/truetype/ttgload.c (load_truetype_glyph): Reintroduce `opened_frame' (removed in a change from 2018-08-26) to handle dealloation of the second frame.
ae3afbc4 2018-08-26 15:40:16 * src/truetype/ttobjs.c (tt_size_read_bytecode): Trace CVT values.
4738dcc4 2018-08-26 12:03:33 Minor tracing adjustments. * src/base/ftstream.c (FT_Stream_EnterFrame, FT_Stream_ExitFrame): Trace. * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Remove tracing.
6e339b8d 2018-08-26 11:59:02 [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.
45524679 2018-08-22 10:31:05 [truetype] Improve legibility of `glyf' parsing. * src/truetype/ttgload.c (ON_CURVE_POINT, X_SHORT_VECTOR, Y_SHORT_VECTOR, REPEAT_FLAG, X_POSITIVE, SAME_X, Y_POSITIVE, SAME_Y, OVERLAP_SIMPLE): New macros. (TT_Load_Simple_Glyph): Use new macros to make code more readable. Remove useless adjustment of `outline->tags' elements.
a0dd16fb 2018-08-15 18:13:17 Don't use `trace_' prefix for FT_COMPONENT arguments. * include/freetype/internal/ftdebug.h (FT_TRACE_COMP, FT_TRACE_COMP_): New auxiliary macros to add `trace_' prefix. (FT_TRACE): Use `FT_TRACE_COMP'. */* (FT_COMPONENT): Updated.
1d7b034c 2018-08-14 15:48:17 Use formatting string in FT_TRACEX calls for non-simple arguments. * src/psaux/cffdecode.c (cff_decoder_parse_charstrings) <cff_op_hstem, cff_op_hintmask, cff_op_hlineto, cff_op_vhcurveto>: Do it. * src/psaux/pshints.c (cf2_hintmap_build): Ditto. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM, cf2_cmdVSTEM, cf2_cmdHLINETO, cf2_cmdRRCURVETO, cf2_cmdCALLSUBR, cf2_escHSTEM3, cf2_cmdHINTMASK, cf2_cmdHVCURVETO>: Ditto. * src/truetype/ttinterp.c (TT_RunIns): Ditto.
720ae67f 2018-08-05 07:21:10 * src/truetype/ttgload.c (compute_glyph_metrics): Fix overflow. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=777151
ced9c311 2018-08-04 07:03:57 Ditto.
be81acc4 2018-08-04 07:01:04 * src/truetype/ttinterp.c (opcode_name): Fix typos.
c9edca8e 2018-07-27 10:44:01 [truetype] Make `TT_Set_MM_Blend' idempotent (#54388). * src/truetype/ttgxvar.c (tt_set_mm_blend): Correctly set `face->doblend' if the current call to the function yields the same blend coordinates as the previous call.
71e29fe1 2018-07-24 10:04:23 [truetype] Match ttdebug's naming of instruction mnemonics. * src/truetype/ttinterp.c: The form used in ttdebug, "MDRP[G,B,W,?]", etc., is slightly more readable than "MDRP[00,01,02,03]".
839cb404 2018-07-16 05:45:45 * src/truetype/ttgxvar.c (tt_set_mm_blend): Fix off-by-one error. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9412
6ceeb87f 2018-07-05 22:31:10 Fix more 32bit issues (#54208) * src/cff/cffload.c (cff_blend_build_vector): Convert assertion into run-time error. * src/truetype/ttgxvar.c (ft_var_to_normalized): Protect against numeric overflow.
207ca38f 2018-06-25 18:50:00 [truetype] Fix memory leak. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Add initializers. Fix typo in `goto' destination. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9071
589d1f08 2018-06-25 18:38:04 * src/truetype/ttgxvar.c (tt_face_vary_cvt): Add initializers. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=9070
a632fb54 2018-06-24 15:22:10 [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 16.16 format arrays, and add the accumulated values to the glyph coordinates at the end of the function.
9b31c446 2018-06-14 21:30:43 Replace `FT_Get_GlyphLayers' with `FT_Get_Color_Glyph_Layer'. This avoids any additional allocation of COLR related structures in a glyph slot. * include/freetype/freetype.h (FT_Glyph_Layer, FT_Glyph_LayerRec, FT_Get_GlyphLayers): Removed. * include/freetype/internal/ftobjs.h (FT_Colr_InternalRec): Removed. (FT_Slot_InternalRec): Remove `color_layers'. * include/freetype/internal/sfnt.h (TT_Load_Colr_Layer_Func): Removed. (SFNT_Interface, FT_DEFINE_SFNT_INTERFACE): Remove `load_colr_layer'. * src/base/ftobjs.c (ft_glyph_slot_done): Updated. (FT_Render_Glyph_Internal): Use `FT_Get_Color_Glyph_Layer'.

9ac9060d 2018-06-03 09:01:17 [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.

2dd20916 2018-05-15 09:05:53 [sfnt] If `COLR' is present, don't assume that all glyphs use it. * src/sfnt/ttcolr.c (tt_face_load_colr_layers): Return FT_Err_Ok if current glyph is not a `COLR' base glyph. * src/truetype/ttgload.c (TT_Load_Glyph): Don't allocate `color_layers' if there are no color layers.
f04d8175 2018-05-13 03:25:09 [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 `colr_and_cpal' field. * include/freetype/internal/tttags. (TTAG_COLR, TTAG_CPAL): New macros. * src/sfnt/ttcolr.c, src/sfnt/ttcolr.h: New files. * src/base/ftobjs.c (ft_glyphslot_done, FT_Render_Glyph_Internal): Handle glyph color layers. * src/sfnt/Jamfile (_sources), src/sfnt/rules.mk (SFNT_DRV_SRC): Add `ttcolr.c'. * src/sfnt/sfdriver.c: Include `ttcolr.h'.
