dd6330d7	2017-12-27T08:06:47	Add missing ChangeLog entry, copyright notices, whitespace, formatting.
a956e36c	2017-12-25T12:34:37	Move PostScript drivers' property handlers to `base' This reduces the amount of duplicated code across PostScript drivers. * src/cff/cffdrivr.c, src/cid/cidriver.c, src/type1/t1driver.c ({cff,cid,t1}_property_{get,set}): Moved to... * include/freetype/internal/ftpsprop.h: ...this new file. (ps_property_{get,set}): New functions to replace moved ones. * src/base/ftpsprop.c: Implement above functions. * include/freetype/internal/internal.h (FT_INTERNAL_POSTSCRIPT_PROPS_H): New macro. * src/cff/cffdrivr.c, src/cid/cidriver.c, src/type1/t1driver.c: Updated. * src/base/Jamfile, src/base/rules.mk, src/base/ftbase.c: Updated.
08cd62de	2017-12-20T22:06:19	Speed up FT_Set_Var_{Design,Blend}_Coordinates if curr == new. We exit early if the current design or blend coordinates are identical to the new ones. * src/truetype/ttgxvar.c (tt_set_mm_blend, TT_Set_Var_Design): Implement it, returning internal error code -1 if there will be no variation change. * src/type1/t1load.c (t1_set_mm_blend): Ditto. * src/base/ftmm.c (FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Updated.
0579d545	2017-12-18T23:45:58	Update incorrect ChangeLog entry.
2df73b39	2017-12-18T23:32:32	[sfnt] Fix charmap type 2 iterator (#52646). The subsetted demo font of the report that exhibits the bug has a very unusual type 2 cmap for Unicode(!): It contains only two sub-headers, one for one-byte characters (covering the range 0x20 to 0xFA), and a second one for higher byte 0x01 (just for character code U+0131). Before this commit, the iterator wasn't able to correctly handle a sub-header for higher byte 0x01. * src/sfnt/ttcmap.c (tt_cmap2_char_next): Fix character increment for outer loop.
bdab6578	2017-12-18T20:45:17	[truetype] Minor code beautification. * src/truetype/ttgxvar.c (ft_var_to_normalized): Trace number of design coordinates. Simplify code.
068a7a03	2017-12-18T20:34:05	* src//: Only use `ft_' and `FT_' variants of stdc library stuff.
2fe272ac	2017-12-18T19:40:07	* src/truetype/ttgxvar.c (tt_face_vary_cvt): Add size guard (#52688).
d062c54c	2017-12-18T09:41:17	[truetype] Fix previous commit. * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Correctly handle unhinted phantom points, which must be properly scaled.
e7935f29	2017-12-18T07:29:57	[truetype] Don't apply HVAR and VVAR deltas twice (#52683). * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Always adjust `pp1' to `pp4', except if we have an HVAR and/or VVAR table. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Handle alternative code branch identically w.r.t. presence of an HVAR and/or VVAR table.
361af72e	2017-12-17T15:07:02	[truetype] Correctly handle variation font phantom points (#52683). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix phantom point indices.
7d3dfcd4	2017-12-17T08:19:51	Fix incorrect advance width scaling (#52683). * src/base/ftadvance.c (FT_Get_Advances): Always respect the FT_LOAD_NO_SCALE flag if present.
d019097b	2017-12-16T22:00:40	* builds/windows/vc2010/freetype.vcxproj: AfterBuild copy. * objs/.gitignore: Ignore almost everything.
2c048a8a	2017-12-11T19:24:30	Fix compiler warning (#52640). * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Remove unused variable.
a998d484	2017-12-09T14:22:35	* builds/windows/vc2010/freetype.vcxproj: Adjust output directory. This allows builds with different configurations in parallel.
286b0c9f	2017-12-09T09:41:45	Fix `make setup dos', second try (#52622). * builds/detect.mk (dos_setup): Don't use literal `>' character at all. Mixing the different escaping rules from make, dos, and windows is too fragile.
81dea493	2017-12-08T20:32:23	Documentation fixes for the last few commits.
ea68f1c8	2017-12-08T20:15:15	[docmaker] Fix code section parsing. Stuff like { <bla> } confused the parser, which incorrectly treated `<bla>' as a markup tag. * src/tools/docmaker/content.py (ContentProcessor::process_content): Apply `re_markup_tags' only outside of code sections.
98ba0c4a	2017-12-08T18:38:41	New `ftdriver.h' file, covering all driver modules. This reduces redundancy and increases synergy; it also reduces the number of header files. * include/freetype/config/ftheader.h (FT_DRIVER_H): New macro. (FT_AUTOHINTER_H, FT_CFF_DRIVER_H, FT_TRUETYPE_DRIVER_H, FT_PCF_DRIVER_H, FT_TYPE1_DRIVER_H): Make them aliases to FT_DRIVER_H. * include/freetype/ftautoh.h, include/freetype/ftcffdrv.h, include/freetype/ftpcfdrv.h, include/freetype/ftt1drv.h, include/freetype/ftttdrv.h: Replaced with... * include/freetype/ftdriver.h: ...this new file. (FT_CFF_HINTING_ADOBE, FT_T1_HINTING_ADOBE): Renamed to... (FT_HINTING_ADOBE): ... this new macro. (FT_CFF_HINTING_FREETYPE, FT_T1_HINTING_FREETYPE): Renamed to... (FT_HINTING_FREETYPE): ... this new macro. * src//: Updated accordingly.
bef8de2a	2017-12-08T10:02:12	Move `ftdriver.h' to `ftdrv.h'. * include/freetype/internal/ftdriver.h: Renamed to... * include/freetype/internal/ftdrv.h: ... this name. * include/freetype/internal/internal.h (FT_INTERNAL_DRIVER_H): Updated.
e1090c60	2017-12-08T09:54:36	Fix access to uninitalized memory (#52613). Also reported as https://bugs.chromium.org/p/chromium/issues/detail?id=791317 * src/base/ftbitmap.c (ft_bitmap_assure_buffer): If increasing the bitmap size needs a larger bitmap buffer, assure that the new memory areas are initialized also.
99df4919	2017-12-08T09:48:18	Fix `make setup dos' (#52622). * builds/detect.mk (dos_setup): Properly escape literal `>' character.
430e9c37	2017-12-07T19:27:29	.mailmap: Add Ewald.
c3cbb440	2017-12-07T16:26:36	Use ASCII only in public header files (#50858).

63b91548	2017-12-07T14:33:44	Fix `make multi'. * include/freetype/internal/fttrace.h: Remove unused tracing macros. s/pshalgo2/pshalgo/. Add `trace_cffdecode'. * src/pshinter/pshalgo.c (FT_COMPONENT): Updated. * src/cff/cffload.c: Include FT_INTERNAL_POSTSCRIPT_AUX_H. * src/cff/cffobjs.c: Include FT_SERVICE_METRICS_VARIATIONS_H and FT_SERVICE_CFF_TABLE_LOAD_H. * src/cid/cidriver.c: Include FT_INTERNAL_POSTSCRIPT_AUX_H. * src/psaux/cffdecode.c: Include FT_FREETYPE_H and FT_INTERNAL_DEBUG_H. (FT_COMPONENT): Define. * src/psaux/cffdecode.h: Include FT_INTERNAL_POSTSCRIPT_AUX_H. * src/psaux/psauxmod.h: Include FT_INTERNAL_POSTSCRIPT_AUX_H. Declare `cff_builder_funcs' and `ps_builder_funcs'. * src/psaux/psft.c: Include `psobjs.h' and `cffdecode.h'. * src/psaux/psobjs.c : Include `psauxmod.h'.
7ec1345d	2017-12-07T14:21:39	* include/freetype/config/ftheader.h: Some clean-up. This commit removes documentation of deprecated macros and does some minor streamlining.
b85ff564	2017-12-06T23:17:23	* builds/symbian/bld.inf: Updated.
ed7f0913	2017-12-06T23:15:54	New header file `ftparams.h' that collects all parameter tags. * include/freetype/config/ftheader.h (FT_PARAMETER_TAGS_H): New macro. (FT_TRUETYPE_UNPATENTED_H, FT_UNPATENTED_HINTING_H): Define it to `ftparams.h'. * include/freetype/ftautoh.h, include/freetype/ftcffdrv.h, include/freetype/ftincrem.h, include/freetype/ftlcdfil.h, include/freetype/ftsnames.h, include/freetype/ftt1drv.h: Include FT_PARAMETER_TAGS_H. Move FT_PARAM_TAG_XXX definitions to... * include/freetype/ftparams.h: ...this new file. * include/freetype/ttunpat.h: Remove. No longer needed.
71fecc53	2017-12-05T12:06:29	Improve tracing messages by using singular and plural forms. * src//.c: Implement it.
87ddad20	2017-12-04T20:43:30	Update or fix links to use the https protocol instead of http.
337e49cf	2017-12-04T12:36:07	[truetype] Allow shared points in `cvar' table (#52532). * src/truetype/ttgxvar.c (tt_face_vary_cvt): Implement it by copying and adjusting the corresponding code from `TT_Vary_Apply_Glyph_Deltas'.
c18c391b	2017-11-28T12:43:45	[truetype] Improving tracing of composite glyphs. * src/truetype/ttgload.c (TT_Load_Composite_Glyph) [FT_DEBUG_LEVEL_TRACE]: Show composite glyph information.
40db4a99	2017-11-27T22:17:41	Allow (again) encoding vectors with more than 256 elements (#52464). In version 2.6.1, this has been disallowed to better reject malformed fonts; however, this restriction was too strong. This time, we only take the first 256 elements into account, since encoding arrays are always accessed with a 8bit integer, according to the PostScript Language Reference. * src/type1/t1load.c (parse_encoding): Implement it.
7d81ba7e	2017-11-27T07:15:04	Fix last commit (#52522). * builds/freetype.mk: Set `FT_OPTION_H' and `FTOPTION_FLAG' properly if we have `ftoption.h' in `BUILD_DIR'.
8f485199	2017-11-24T10:34:09	[unix] Install a massaged `ftoption.h' file (#51780). * builds/unix/configure.raw (ftoption_set, ftoption_unset): New auxiliary functions to construct... (FTOPTION_H_SED): ... this new variable. Apply it as a sed argument while copying `ftoption.h' to the `builds/unix' directory (using `AC_CONFIG_FILES'). Simplify code of test that checks cpp's computation of bit length (the test previously created an empty `ftoption.h' file and deleted it immediately afterwards); without this change, it can happen on my GNU/Linux box that `configure's execution of `config.status' doesn't create `ftoption.h' (no idea why this happens). * builds/unix/install.mk (install): Install `builds/unix/ftoption.h'. * builds/unix/unix-def.in (DISTCLEAN): Updated. * builds/unix/.gitignore: Updated.
0d0e5bb1	2017-11-23T20:42:57	Minor.
2f1863cf	2017-11-23T20:40:52	Silence unused function warnings. Some static function declarations cause unused function warnings if certain config options are turned off via `ftoption.h'. * src/base/ftbase.h, src/base/ftrfork.c, src/sfnt/ttbdf.h, src/truetype/ttgxvar.h: Add #ifdef guards around these sections.
bec14f68	2017-11-22T18:57:56	* src/psaux/psft.c (cf2_setGlyphWidth): Check format before setting. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=4377
b9bd2d14	2017-11-22T12:32:47	[psaux] Fix CFF advance widths. (#52466) Glyph advance widths were being written to the new `PS_Decoder' but not saved to the underlying format specific decoder. This caused pure CFF fonts to have bad advance width. * include/freetype/internal/psaux.h (PS_Decoder): Change `glyph_width' field to pointer. Remove unused fields. * src/psaux/psobjs.c (ps_decoder_init): Change `glyph_width' from copy to reference. Remove unused. * src/psaux/psft.c (cf2_setGlyphWidth): Update code.
954710dd	2017-11-15T23:06:29	* include/freetype/ftrender.h: Fix `FT_Renderer_RenderFunc' type.
a364e38a	2017-11-14T07:54:53	Use Adobe hinting engine for `light' hinting of both CFF and Type 1. Since Ewald Hew factored the Adobe hinting engine out of the CFF driver code, we can now use it on Type 1 (and CID) font formats, as both have the same hinting philosophy. This change activates the Adobe hinter when in LIGHT mode, and therefore always unless explicitly asking for the auto-hinter. This makes LIGHT behavior consistent with CFF fonts. As of this commit, the hinting engine table looks as follows. LIGHT NORMAL ------------------------- TrueType Auto v40 CFF Adobe Adobe Type 1 Adobe Adobe
af585ad4	2017-11-09T13:38:26	* CMakeLists.txt: Add `DISABLE_FORCE_DEBUG_PREFIX' option.
8f5568bf	2017-11-06T21:42:46	* src/base/ftobjs.c (FT_Load_Glyph): Relocate condition.
ab6fe076	2017-11-06T21:34:56	* src/smooth/ftgrays.c (gray_set_cell): Fix uninitialized variables.
cdab9cfa	2017-10-21T16:36:49	[psaux] Fix PostScript interpreter rewinding in Type 1 mode. (#52251) The interpreter in Type 1 mode rewinds the charstring after collecting all hints for building the initial hintmap (commit d52dd7f). However, some charstrings use `endchar' in a final subroutine call, rewinding to the start of that subroutine, and only a small section of the actual glyph is drawn. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdENDCHAR>: Ensure we are on the top level charstring before rewinding.
77b34e01	2017-11-03T16:13:29	[truetype] Add more tricky fonts. See the report by Yang Yinsen. https://lists.gnu.org/archive/html/freetype-devel/2017-11/msg00000.html * src/truetype/ttobjs.c (trick_names): Add `DFGothic-EB', `DFGyoSho-Lt', `DFHSGothic-W5', `DFHSMincho-W3' and `DFHSMincho-W7'. (tt_check_trickyness_sfnt_ids): Add checksums for DFGothic-EB, DFGyoSho-Lt, DFHSGothic-W5, DFHSMincho-W3 and DFHSMincho-W7. Also add checksums for DLCLiShu and DLCHayBold which their family names were already listed but their checksums were previously unknown.
81651636	2017-11-01T22:51:03	[smooth] Fix complex rendering at high ppem. We used to split large glyphs into horizontal bands and continue bisecting them still horizontally if that was not enough. This is guaranteed to fail when a single scanline cannot fit into the rendering memory pool. Now we bisect the bands vertically so that the smallest unit is a column of the band height, which is guranteed to fit into memory. * src/smooth/ftgrays.c (gray_convert_glyph): Implement it.
91015cb4	2017-10-21T22:57:43	[smooth] Improve complex rendering at high ppem. At large sizes almost but not exactly horizontal segments can quickly drain the rendering pool. This patch at least avoids filling the pool with trivial cells. Beyond this, we can only increase the pool size. Reported, analyzed, and tested by Colin Fahey. * src/smooth/ftgrays.c (gray_set_cell): Do not record trivial cells.
d74440a3	2017-10-20T16:27:33	[base] Improve tracing in FT_Load_Glyph, FT__Size. src/base/ftobjs.c (FT_Load_Glyph): Tag tracing messages with function name, glyph index, and load flags. (FT_Select_Metrics, FT_Request_Metrics): Remove all tracing. (FT_Select_Size, FT_Request_Size): Improve tracing.
c10e7800	2017-10-18T23:05:51	[base] Improve tracing in FT_Render_Glyph. * src/base/ftobjs.c (FT_Render_Glyph_Internal): Add total coverage calculations and downgrade Netpbm dump to bitmap:7.
94f6d57a	2017-10-16T11:48:31	[cff] Fix segfault on missing `psaux' (#52218) * src/cff/cffload.c (cff_done_blend): Add a check for possible nullptr. * modules.cfg: Update dependency list.
ccb0f799	2017-10-15T14:19:13	[base, cff] Fix MSVC warnings. * src/base/ftobjs.c (FT_New_Library): C4702: unreachable code. (ft_glyphslot_preset_bitmap): C4244: possible loss of data. * src/cff/cffload.c (cff_blend_doBlend): C4244: possible loss of data. Turn `sum' into unsigned.
6bea49e0	2017-10-14T22:45:11	[base] Netpbm image tracing. * src/base/ftobjs.c (FT_Load_Glyph): Trace bitmap size. (FT_Render_Glyph_Internal): Trace bitmap in Netpbm format. * src/smooth/ftgrays.c (gray_sweep): Sweep remnants of span tracing.
73840852	2017-10-14T22:22:27	* builds/windows/ftdebug.c (FT_Message): Print to stderr. * builds/wince/ftdebug.c (FT_Message): Ditto.
90461c01	2017-10-14T08:42:07	[afshaper] Delay creating `hb_set' objects until needed. In runs on Noto Naskh Arabic, this results in 89 sets created instead of 340 before. Makes auto-hinter setup with HarfBuzz enabled 20% to 30% faster. * src/autofit/afshaper.c (af_shaper_get_coverage): Implement it.
d2b3b9e6	2017-10-12T18:48:57	* devel/ftoption.h: Enable T1_CONFIG_OPTION_OLD_ENGINE by default.
7e23568b	2017-10-12T18:13:22	[type1, cid] Add hinting engine switch. Implement property service in `type1' and `cid' drivers to allow switching between FreeType or Adobe hinting engine when both are available. * src/cid/cidriver.c (cid_property_{set,get}, cid_services), src/type1/t1driver.c (t1_property_{set,get}, t1_services): Add Properties service. * src/cid/cidobjs.c (cid_driver_init), src/type1/t1objs.c (T1_Driver_Init): Add default property values.
dff40d03	2017-10-12T18:13:21	Add T1_CONFIG_OPTION_OLD_ENGINE configuration option. This controls whether the old Type 1 engine gets compiled into FreeType. It is disabled by default. * devel/ftoption.h, include/freetype/config/ftoption.h (T1_CONFIG_OPTION_OLD_ENGINE): New macro. * include/freetype/internal/psaux.h (PS_Decoder): Remove unused field. * include/freetype/internal/psaux.h, src/cid/cidgload.c (cid_load_glyph), src/psaux/psauxmod.c, src/psaux/psobjs.c (ps_builder_add_point), src/psaux/t1decode.c (t1_lookup_glyph_by_stdcharcode, t1_decoder_parse_glyph, t1operator_seac, t1_decoder_parse_charstrings), src/psaux/t1decode.h, src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Surround relevant code with macro. Minor code changes.
78df3c27	2017-10-12T18:13:08	Extract width parsing from Type 1 parser. Duplicate the fast advance width calculations from the old parser. This is to facilitate adding options for compiling out the old parser. * src/psaux/t1decode.{c,h} (t1_decoder_parse_metrics): New function. * include/freetype/internal/psaux.h (T1_Decoder_Funcs): New entry `parse_metrics'. * src/psaux/psauxmod.c: Set the new entry. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Separate conditional for selecting engine.
8768536c	2017-10-12T00:13:51	[autofit] Better visualize table tracing in source code.
64985519	2017-10-09T07:45:03	* src/base/ftoutln.c (FT_Outline_Translate): Fix integer overflow. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=772775
b7e43f7d	2017-10-08T11:58:39	* src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Integer overflows. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3579
08e2e311	2017-10-08T10:37:50	Document global size metrics needed for native bytecode hinting (#52165).

7bfcaaca	2017-10-07T13:14:38	[sfnt] Adjust behaviour of PS font names for variation fonts. * src/sfnt/sfdriver.c (sfnt_get_var_ps_name): Use a named instance's PS name only if no variation is applied.
f89c67f0	2017-10-07T13:10:53	[cff, truetype] Adjust behaviour of named instances. This commit completely separates the interaction between named instances and variation functions. In particular, resetting the variation returns to the current named instance (if set) and not to the base font. As a side effect, variation functions no longer change the named instance index. * src/cff/cffobjs.c (cff_face_init): Use MM service's `set_instance' function. Also apply `MVAR' table to named instances. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Add cast. (tt_set_mm_blend): No longer check whether requested variation coincides with a named instance. (TT_Set_Var_Design): Use current named instance for default coordinates. * src/truetype/ttobjs.c (tt_face_init): Use `TT_Set_Named_Instance'.
e9ef538a	2017-10-07T12:57:11	Make `FT_Set_Named_Instance' work. * src/cff/cffdrivr.c (cff_set_instance): New function.

8c92f762	2017-10-07T12:12:49	Make `FT_FACE_FLAG_VARIATION' work. * include/freetype/internal/tttypes.h (TT_Face): Remove `is_default_instance'; this can be replaced with a combination of `FT_IS_VARIATION' and `FT_IS_INSTANCE'. * src/cff/cffdrivr.c (cff_get_advances): Updated. * src/sfnt/sfdriver.c (sfnt_get_ps_name), src/sfnt/sfobjs.c (sfnt_init_face): Updated. * src/truetype/ttdriver.c (tt_get_advances), src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph, IS_DEFAULT_INSTANCE), src/truetype/ttgxvar.c (tt_set_mm_blend): Updated. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design): Handle `FT_FACE_FLAG_VARIATION'. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_Design): Handle `FT_FACE_FLAG_VARIATION'.
dd8539ef	2017-10-07T11:40:03	New function `FT_Set_Named_Instance'. No effect yet. * src/base/ftmm.c (FT_Set_Named_Instance): New function. * include/freetype/ftmm.h: Updated.
b3f9c4f2	2017-10-07T11:34:23	Add macros for checking whether a font variation is active. * include/freetype/freetype.h (FT_FACE_FLAG_VARIATION, FT_IS_VARIATION): New macros. No effect yet.
e23fe2ad	2017-10-07T11:25:04	Add framework for setting named instance in MM service. * include/freetype/internal/services/svmm.h (FT_Set_Instance_Func): New function typedef. (MultiMasters): Add `set_instance' member. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. * src/cff/cffdrivr.c (cff_service_multi_masters), src/truetype/ttdriver (tt_service_gx_multi_masters), src/type1/t1driver.c (t1_service_multi_masters): Updated.

[sfnt] Fix charmap type 2 iterator (#52646). The subsetted demo font of the report that exhibits the bug has a very unusual type 2 cmap for Unicode(!): It contains only two sub-headers, one for one-byte characters (covering the range 0x20 to 0xFA), and a second one for higher byte 0x01 (just for character code U+0131). Before this commit, the iterator wasn't able to correctly handle a sub-header for higher byte 0x01. * src/sfnt/ttcmap.c (tt_cmap2_char_next): Fix character increment for outer loop.

Allow (again) encoding vectors with more than 256 elements (#52464). In version 2.6.1, this has been disallowed to better reject malformed fonts; however, this restriction was too strong. This time, we only take the first 256 elements into account, since encoding arrays are always accessed with a 8bit integer, according to the PostScript Language Reference. * src/type1/t1load.c (parse_encoding): Implement it.

Apply it as a sed argument while copying `ftoption.h' to the `builds/unix' directory (using `AC_CONFIG_FILES'). Simplify code of test that checks cpp's computation of bit length (the test previously created an empty `ftoption.h' file and deleted it immediately afterwards); without this change, it can happen on my GNU/Linux box that `configure's execution of `config.status' doesn't create `ftoption.h' (no idea why this happens). * builds/unix/install.mk (install): Install `builds/unix/ftoption.h'. * builds/unix/unix-def.in (DISTCLEAN): Updated. * builds/unix/.gitignore: Updated.

Use Adobe hinting engine for `light' hinting of both CFF and Type 1. Since Ewald Hew factored the Adobe hinting engine out of the CFF driver code, we can now use it on Type 1 (and CID) font formats, as both have the same hinting philosophy. This change activates the Adobe hinter when in LIGHT mode, and therefore always unless explicitly asking for the auto-hinter. This makes LIGHT behavior consistent with CFF fonts. As of this commit, the hinting engine table looks as follows. LIGHT NORMAL ------------------------- TrueType Auto v40 CFF Adobe Adobe Type 1 Adobe Adobe

[psaux] Fix PostScript interpreter rewinding in Type 1 mode. (#52251) The interpreter in Type 1 mode rewinds the charstring after collecting all hints for building the initial hintmap (commit d52dd7f). However, some charstrings use `endchar' in a final subroutine call, rewinding to the start of that subroutine, and only a small section of the actual glyph is drawn. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdENDCHAR>: Ensure we are on the top level charstring before rewinding.

[truetype] Add more tricky fonts. See the report by Yang Yinsen. https://lists.gnu.org/archive/html/freetype-devel/2017-11/msg00000.html * src/truetype/ttobjs.c (trick_names): Add `DFGothic-EB', `DFGyoSho-Lt', `DFHSGothic-W5', `DFHSMincho-W3' and `DFHSMincho-W7'. (tt_check_trickyness_sfnt_ids): Add checksums for DFGothic-EB, DFGyoSho-Lt, DFHSGothic-W5, DFHSMincho-W3 and DFHSMincho-W7. Also add checksums for DLCLiShu and DLCHayBold which their family names were already listed but their checksums were previously unknown.

[smooth] Fix complex rendering at high ppem. We used to split large glyphs into horizontal bands and continue bisecting them still horizontally if that was not enough. This is guaranteed to fail when a single scanline cannot fit into the rendering memory pool. Now we bisect the bands vertically so that the smallest unit is a column of the band height, which is guranteed to fit into memory. * src/smooth/ftgrays.c (gray_convert_glyph): Implement it.

[smooth] Improve complex rendering at high ppem. At large sizes almost but not exactly horizontal segments can quickly drain the rendering pool. This patch at least avoids filling the pool with trivial cells. Beyond this, we can only increase the pool size. Reported, analyzed, and tested by Colin Fahey. * src/smooth/ftgrays.c (gray_set_cell): Do not record trivial cells.

[cff, truetype] Adjust behaviour of named instances. This commit completely separates the interaction between named instances and variation functions. In particular, resetting the variation returns to the current named instance (if set) and not to the base font. As a side effect, variation functions no longer change the named instance index. * src/cff/cffobjs.c (cff_face_init): Use MM service's `set_instance' function. Also apply `MVAR' table to named instances. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Add cast. (tt_set_mm_blend): No longer check whether requested variation coincides with a named instance.
