1f271751	2019-04-11T23:48:21	[smooth] Fix segfault in direct mode (#56092). * src/base/ftoutln.c (FT_Outline_Render): Set missing clip_box for direct mode. * src/smooth/ftgrays.c (gray_raster_render): Use it.
f0384d5f	2019-04-09T11:01:24	Minor.
885b4c24	2019-04-06T07:07:37	* src/sfnt/ttcmap.c (tt_get_glyph_name): Pacify compiler (#56061). This is for Visual Studio 2019 on ARM.
3ad1c93a	2019-04-06T06:37:42	Make `glyph_name' parameter to `FT_Get_Name_Index' a `const'. * include/freetype/freetype.h (FT_Get_Name_Index), include/freetype/internal/ftobjs.h (FT_Face_GetGlyphNameIndexFunc), include/freetype/internal/services/svgldict.h (FT_GlyphDict_NameIndexFunc), src/base/ftobjs.c (FT_Get_Name_Index), src/cff/cffdrivr.c (cff_get_name_index), src/sfnt/sfdriver.c (sfnt_get_name_index), src/type1/t1driver.c (t1_get_name_index), src/type42/t42drivr.c (t42_get_name_index): Add `const' to second argument.
6986ddac	2019-03-31T11:08:49	[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. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=12137
df266d3e	2019-03-20T07:04:06	[autofit] Fix Mongolian blue zone characters. * src/autofit/afblue.dat: Use U+200D (ZERO-WIDTH JOINER) characters to get medial forms for some Mongolian characters. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
dde03eec	2019-03-19T10:50:38	[autofit] Add support for Mongolian script. As a de-facto standard, layouts using this script are constructed horizontally line by line, then the lines are rotated clockwise for vertical display. * src/autofit/afblue.dat: Add blue zone data for Mongolian. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Mongolian standard characters. * src/autofit/afranges.c, src/autofit/afstyles.h: Add Mongolian data.
fbbcf503	2019-03-15T07:27:02	* Version 2.10.0 released. ========================== Tag sources with `VER-2-10-0'. * docs/VERSION.TXT: Add entry for version 2.10.0. * docs/CHANGES: Updated. * README, Jamfile (RefDoc), src/base/ftver.rc, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.9.1/2.10.0/, s/291/2100/. * include/freetype/freetype.h (FREETYPE_MINOR): Set to 10. (FREETYPE_PATCH): Set to 0. * builds/unix/configure.raw (version_info): Set to 23:0:17. * CMakeLists.txt (VERSION_MINOR): Set to 10. (VERSION_PATCH): Set to 0. * builds/toplevel.mk (version, winversion): Since the minor version number has two digits now, never omit the patch number. We would get ambiguous zip file names otherwise. (dist): Remove remnants of `docmaker' tool. (do-dist): Remove unused intermediate files. * src/cff/cffparse.c (destrict_c2s_item): Guard function with CFF_CONFIG_OPTION_OLD_ENGINE macro.
2f4b740c	2019-03-07T09:42:25	Fix invalid function pointer casts. This change should allow Freetype to work on WASM/Emscripten without needing `-s EMULATE_FUNCTION_POINTER_CASTS=1'. * src/autofit/afdummy.c (af_dummy_hints_apply): Fix signature. * src/cid/cidload.c (cid_parse_font_matrix, parse_fd_array, parse_expansion_factor, parse_font_name): Return `void', not `FT_Error'. * include/freetype/internal/ftobjs.h (FT_CMap_CharVarIsDefaultFunc): Fix signature.
31757f96	2019-03-05T11:35:03	[base] Handle numeric overflow (#55827). * src/base/ftglyph.c (FT_Glyph_Get_CBox): Use `FT_PIX_CEIL_LONG'.
6a4718a3	2019-03-05T17:25:19	Fix use of uninitialized memory. * src/psaux/psintrp.c (cf2_interpT2CharString): The call to `cf2_arrstack_setCount' may fail because the allocator ran out of 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.
4d51f78d	2019-02-23T11:21:48	More documentation updates. In particular, mark the new behaviour of `FT_LOAD_COLOR' as experimental.
6ab36880	2019-02-23T11:18:39	* src/base/ftbitmap.c (FT_Bitmap_Blend): No fractional offsets. The function only provided a framework without an actual implementation, which this commits removes.
75859970	2019-02-23T10:07:09	Update all copyright notices.
fd8fc64e	2019-02-23T10:05:37	* src/tools/update-copyright-year: Insert `(C)'.
b77826e1	2019-02-21T10:23:15	Triage 8ea854bfe92443706d55656072f891ec8f2cb3c2.
8ea854bf	2019-02-21T10:14:57	[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
5e3a38b1	2019-02-21T10:04:28	[psaux] Mask numeric overflow. * src/psaux/cffdecode.c (cff_decoder_parse_charstrings): Mask numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=13041
de8de1ce	2019-02-20T12:48:36	Minor (whitespace, spelling, doc update).
0ac69211	2019-02-16T07:05:39	* src/autofit/afwarp.h (af_warper_compute): Fix declaration.
b66d6a91	2019-02-06T07:38:25	CHANGES: Document recent metrics change from Nikolaus.
a6feefdf	2019-02-02T15:50:57	[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.
f72b0074	2019-02-02T15:45:31	[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.
f686ad46	2019-01-22T20:31:44	Update copyright years.
f61f49fe	2019-01-18T13:25:23	[sfnt] Handle TT fonts having two PostScript font names (#55471). * src/sfnt/sfdriver.c (sfnt_get_name_id): Prefer English over any other language found for PostScript font names.
1e7a8f30	2019-01-08T20:54:13	[psaux, type1] Align tracing.
b75abeb5	2019-01-08T20:51:39	[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'.
b89166cc	2018-12-29T08:55:01	* src/autofit/aflatin2.c: Some fixes from `aflatin.c' (#55310).
afa043de	2018-12-25T22:44:05	Fix links (mostly http -> https).
5e029659	2018-12-25T19:24:06	* src/psaux/cffdecode.c (cff_operaor_seac): Fix numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11915
ec439711	2018-12-12T19:59:42	[gxvalid] Fix compiler warnings. * src/gxvalid/gxvjust.c (gxv_just_check_max_gid), src/gxvalid/gxvmort.c (gxv_mort_coverage_validate): Use `FT_UNUSED'.
2b4e61e4	2018-12-12T09:36:39	Minor documentation fixes.
3e8a2283	2018-12-11T23:54:17	* 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.
f1b6183f	2018-12-04T11:51:15	[bdf] Ignore data after `ENDFONT'. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10798 * src/bdf/bdflib.c (_bdf_parse_end): New function. (_bdf_parse_glyphs): Switch to `_bdf_parse_end' after `ENDFONT' has been encountered.
78a1e695	2018-11-27T22:24:06	[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.
1fc6937f	2018-11-27T18:02:44	[cff] Fix compiler warning (#55105). * src/cff/cffparse.c (cff_parser_run): Guard label only used if CFF_CONFIG_OPTION_OLD_ENGINE is active.
74cdd75f	2018-11-27T17:55:40	[truetype] Fix numeric overflow (#55103). * src/truetype/ttgload.c (compute_glyph_metrics): Use `SUB_LONG'.
55b35cd6	2018-11-22T11:43:48	* src/cff/cffparse.c: Please the compiler.
642bc759	2018-11-22T10:29:35	[cff] Fix memory overflow.

78db9eec	2018-11-10T15:39:19	[smooth] Placeholder only for library-enabled LCD filtering. * src/smooth/ftsmooth.c (ft_smooth_init): Add disabled `FT_Library_SetLcdFilter' call.
58e48e92	2018-11-09T12:14:35	[psaux] Add safety guard (#54985). * src/psaux/psobjs.c (cff_builder_close_contour): Do it.
181033d3	2018-11-08T21:04:56	[ftstroke] Fix unpredictable failures (#54986). * src/base/ftstroke.c (ft_sroke_border_lineto): Fix lineto check.
81c31f62	2018-11-08T07:54:47	[ftstroke] Fix unpredictable failures (#54976). * src/base/ftstroke.c (ft_sroke_border_close): Set the start tags.
fb0d66d0	2018-11-07T00:47:44	[truetype] Fix VF check from 2018-09-12 (#54973). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Use correct offsets for estimates.
fbd24523	2018-11-06T11:15:31	[pshinter] Fix numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11242 * src/pshinter/pshrec.c (ps_dimension_add_t1stem): Implement it.
5b86f53d	2018-11-06T11:08:41	[psaux] Fix timeout in old CFF engine. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11260 * src/psaux/cffdecode.c (cff_decoder_parse_charstrings) <cff_op_sqrt> [CFF_CONFIG_OPTION_OLD_ENGINE]: Fix potential endless loop.
cc288e38	2018-11-04T22:09:16	Minor.
1f43affc	2018-11-04T13:11:16	* src/truetype/ttgxvar.c: Use enum definitions.

ce3feb0b	2018-11-03T22:43:21	Revert due to specs: [truetype] Speed up variation IUP. This reverts commit 1e4496c54c010843c1bac56e5d344115d1a49620.
dfa86d65	2018-11-03T22:36:52	Revert "[truetype] Speed up variation IUP." This reverts commit 1e4496c54c010843c1bac56e5d344115d1a49620.
61d50756	2018-11-02T20:42:25	* src/truetype/ttgxvar.c (ft_var_get_item_delta): Fixed logic. Reported and tested by Behdad.
339c451a	2018-11-02T10:10:10	[autofit] Prevent SEGV. See https://bugs.ghostscript.com/show_bug.cgi?id=697545 for more details on how the bug was found. * src/autofit/afloader.c (af_loader_load_glyph): Propagate error code.
1e4496c5	2018-10-31T23:17:33	[truetype] Speed up variation IUP. * src/truetype/ttgxvar.c (tt_delta_interpolate): Separate trivial snapping to the same position from true interpolation.
ba03310b	2018-10-31T22:01:36	* src/type1/t1load.c (t1_set_mm_blend): Optimized.
300da33d	2018-10-31T21:55:40	* src/truetype/ttgxvar.c (ft_var_get_item_delta): Optimized.
c13635ee	2018-10-29T21:25:10	[base] Fix numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11080 * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use `MUL_LONG'.
ba62f9d8	2018-10-29T21:11:36	[cff] Fix numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10988 * src/cff/cffparse.c (cff_parser_run) [CFF_CONFIG_OPTION_OLD_ENGINE]: Use `NEG_LONG'.
3e8ec291	2018-10-26T23:23:48	[sfnt] Make `head' timestamps unsigned. It's been more than 2^31 seconds since 1904. * include/freetype/tttables.h (TT_Header): Change field types. * src/sfnt/ttload.c (tt_face_load_generic_header): Updated.
d71f2bc1	2018-10-26T22:52:25	Revert "Align FreeType with standard C memory management." This reverts commit 877aa1b2cc662978aae61ed4d5c6ea8ba56b2fe7.
bfe53294	2018-10-27T00:07:53	[psaux] Fix numeric overflow. Triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11157 * src/psaux/cffdecode.c (cff_decoder_parse_charstrings) <cff_op_blend> [CFF_CONFIG_OPTION_OLD_ENGINE]: Fix integer overflow.
f56830ed	2018-10-20T07:27:47	Avoid endless loop while tracing (#54858). * src/type1/t1load.c (parse_buildchar): Guard tracing stuff with FT_DEBUG_LEVEL_TRACE.
912e174c	2018-10-07T09:28:52	A missing Unicode cmap is not a fatal error. This is a follow-up to the previous commit. * src/cff/cffobjs.c (cff_face_init), src/sfnt/sfobjs.c (sfnt_load_face), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Implement it.
885f5b0b	2018-10-07T09:03:05	Fix handling of FT_CONFIG_OPTION_ADOBE_GLYPH_LIST (#54794). * src/cff/cffcmap.c (cff_cmap_unicode_init), src/psaux/t1cmap.c (t1_cmap_unicode_init), src/sfnt/ttcmap.c (tt_cmap_unicode_init): Check `unicodes_init' field.
0a178144	2018-10-07T08:59:56	Whitespace.
f262d15d	2018-10-07T07:40:37	Minor comment improvement.
9817571c	2018-10-03T08:04:55	[ftgrays] Fix typo in stand-alone mode (#54771). * src/smooth/ftgrays.c (FT_THROW) [STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: Fix call to `FT_ERR_CAT'.
d280ae1e	2018-10-02T20:45:16	[psaux] Fix segfault. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10768 * src/psaux/cffdecode.c (cff_decoder_parse_charstrings) <cff_op_callothersubr> [CFF_CONFIG_OPTION_OLD_ENGINE]: Check argument.
6b660f12	2018-10-02T16:48:59	[psaux] Fix numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10768 * src/psaux/cffdecode.c (cff_decoder_parse_charstrings) <cff_op_roll> [CFF_CONFIG_OPTION_OLD_ENGINE]: Use NEG_INT.
83fc524d	2018-10-02T16:36:49	[pshinter] Handle numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10550 * src/pshinter/pshglob.c (psh_blues_snap_stem): Mask numeric overflow.
877aa1b2	2018-09-27T21:17:36	Align FreeType with standard C memory management. * include/freetype/ftsystem.h: Include FT_TYPES_H. (FT_Alloc_Func, FT_Realloc_Func): Use size_t for the size arguments. * src/raster/ftmisc.h: Ditto. * builds/amiga/src/base/ftsystem.c, builds/unix/ftsystem.c, * builds/vms/ftsystem.c, src/base/ftsystem.c (ft_alloc, ft_realloc): Use size_t for the size arguments. * src/base/ftdbgmem.c (ft_mem_debug_alloc, ft_mem_debug_realloc): Use FT_Offset, aka size_t, for the size arguments.
4500c701	2018-09-26T22:04:50	Typo.
a9af6914	2018-09-25T09:10:09	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.
0f122fef	2018-09-23T21:46:26	[bdf] Speed up charmap access. This makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times faster. * src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Help binary search with continuous prediction.
793a9ff9	2018-09-22T14:38:00	* src/base/ftobjs.c (ft_glyphslot_reset_bimap): Another tweak. This one should be clearer. When the rounded monochrome bbox collapses we add a pixel that covers most if not all original cbox.
f26d5775	2018-09-21T20:34:58	* src/base/ftobjs.c (ft_glyphslot_reset_bimap): Further tweak.
335528e1	2018-09-21T11:26:37	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.
c168cc3b	2018-09-21T11:09:27	[raster] Fix disappearing vertical lines (#54589). * src/raster/ftraster.c (Vertical_Sweep_Span): Handle special case where both left and right outline exactly pass pixel centers.
493aa68f	2018-09-21T08:32:22	[base] Some comments.
2a9850c4	2018-09-20T22:40:32	* src/base/ftobjs.c (ft_glyphslot_reset_bimap): Tiny rounding tweak. This adds pixels in case a contour goes through the center and they need to be turned on in the b/w rasterizer.
c1b21f47	2018-09-20T22:14:46	[pcf] Replace charmap implementation. PCF comes with charmap lookup table, aka PCF encodings. Using it directly makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times faster than the original BDF-like binary searches. * src/pcf/pcf.h (PCF_EncodingRec): Removed.

[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.

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

2019-02-02T15:50:57

[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.

2019-02-02T15:45:31

[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.

[pcf] Replace charmap implementation. PCF comes with charmap lookup table, aka PCF encodings. Using it directly makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times faster than the original BDF-like binary searches. * src/pcf/pcf.h (PCF_EncodingRec): Removed.
