9ac9060d	2018-06-03T09:01:17	[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.
95149592	2018-05-02T20:27:48	Remove FT_CONFIG_OPTION_PIC and related code. / [FT_CONFIG_OPTION_PIC]: Remove all code guarded by this preprocessor symbol. /: Replace `XXX_GET' macros (which could be either a function in PIC mode or an array in non-PIC mode) with `xxx' arrays. * include/freetype/internal/ftpic.h, src/autofit/afpic.c, src/autofit/afpic.h, src/base/basepic.c, src/base/basepic.h, src/base/ftpic.c, src/cff/cffpic.c, src/cff/cffpic.h, src/pshinter/pshpic.c, src/pshinter/pshpic.h, src/psnames/pspic.c, src/psnames/pspic.h, src/raster/rastpic.c, src/raster/rastpic.h, src/sfnt/sfntpic.c, src/sfnt/sfntpic.h, src/smooth/ftspic.c, src/smooth/ftspic.h, src/truetype/ttpic.c, src/truetype/ttpic.h: Removed.

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.

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'.

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'.
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.

1df35d94	2017-10-04T22:46:36	[cff] Add support for `FSType'. * include/freetype/internal/cfftypes.h (CFF_FontRec): Add `font_extra' entry. * src/cff/cffdrivr.c (cff_ps_get_font_extra): New function to retrieve FSType info from the embedded PostScript data. (cff_service_ps_info): Register function. * src/cff/cffload.c (cff_font_done): Free `font_extra'.

ebb1735a	2017-09-25T08:26:57	Move `psdecode' into `psobjs'. As the former only contains a single procedure, move it into `psobjs' for simplicity. Also change the parameter order to the conventional one. * src/psaux/psdecode.c (ps_decoder_init): Moved to... * src/psaux/psobjs.c: ...Here. * src/psaux/psdecode.h, src/psaux/psobjs.h: Ditto. * include/freetype/internal/psaux.h (PSAux_ServiceRec): Update `ps_decoder_init' function signature. * src/cff/cffgload.c, src/cid/cidgload.c, src/type1/t1gload.c: Update calls. * src/psaux/psaux.c, src/psaux/psauxmod.c: Update includes. * src/psaux/Jamfile (_sources), src/psaux/rules.mk (PSAUX_DRV_SRC): Update file references.

b00be9f6	2017-09-19T07:12:03	[cff] Fix family name logic of pure CFF fontdata (#52056). 1. If `FamilyName' is present in the CFF font, use this for FT_Face's `family_name'. 2. Otherwise, use the face name and chop off any subset prefix. 3. If at this point FT_Face's `family_name' is set, use this together with the full name to determine the style. 4. Otherwise, use `CIDFontName' as FT_Face's `family_name'. 5. If we don't have a valid style, use "Regular". Previously, FT_Face's `family_name' entry for pure CFF fontdata nearly always was the fontname itself, instead of the `FamilyName' entry in the CFF font (assuming there is one). * src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.

[cff, truetype] Adjust behaviour of named instances. This commit completely separates the interaction between named instances and variation functions.

[cff] Fix family name logic of pure CFF fontdata (#52056). 1. If `FamilyName' is present in the CFF font, use this for FT_Face's `family_name'. 2. Otherwise, use the face name and chop off any subset prefix. 3. If at this point FT_Face's `family_name' is set, use this together with the full name to determine the style. 4. Otherwise, use `CIDFontName' as FT_Face's `family_name'. 5. If we don't have a valid style, use "Regular". Previously, FT_Face's `family_name' entry for pure CFF fontdata nearly always was the fontname itself, instead of the `FamilyName' entry in the CFF font (assuming there is one). * src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.

[cff] s/cf2_floatToFixed/cf2_doubleToFixed/. The new name better describes what the macro actually does; additionally, we don't need a trailing `f' for literals (there was only a single such instance in the code, but this caused a clang warning because the macro itself uses `double' literals). * src/cff/cf2blues.c, src/cff/cf2blues.h, src/cff/cf2fixed.h, src/cff/cf2font.c, src/cff/cf2hints.c: Updated.
