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.

3a406127	2013-01-16T19:48:31	[truetype] Improve sub-pixel code. This patches fixes many issues with the ttsubpix implementation. 1. Data tables are defined, instead of declared, in the header, and thus copied into each source file that includes it. 2. These tables were defined as global, mutable, visible variables, and thus costing private RAM to every process that loads the library (> 50 KB / process, this is huge!). Additionally, this also made the library export the symbols completely needlessly. 3. Missing `sph_' and `SPH_' prefixes to some of the definitions. Note that this doesn't try to fix the incredibly inefficient storage format for the data tables used by the code. This one will require another pass in the future. * src/truetype/ttinterp.h (MAX_NAME_SIZE, MAX_CLASS_MEMBERS): Renamed to... (SPH_MAX_NAME_SIZE, SPH_MAX_CLASS_MEMBERS): This. Update all users. (SPH_TweakRule, SPH_ScaleRule): Decorate with `const' where appropriate. (Font_Class): Rename to... (SPH_Font_Class): This. Decorate with `const' where appropriate. * src/truetype/ttsubpix.h (scale_test_tweak, sph_test_tweak): Decorate arguments with `const' where appropriate. Move font tweaking tables to... * src/truetype/ttsubpic.c: This file and decorate them with `static' and `const' where appropriate. (X_SCALING_Rules, X_SCALING_RULES_SIZE): Renamed to...

79e36bae	2012-06-18T10:36:06	[truetype] Support subpixel hinting. This is the large, famous `Infinality' patch to support ClearType bytecode which has been available from http://www.infinality.net/blog/ for some time, and which has been refined over the last years. While still experimental, it is now mature enough to be included directly into FreeType. Most of the code is based on the ClearType whitepaper written by Greg Hitchcock http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx which gives a detailed overview of the necessary changes to the Microsoft rasterizer so that older fonts are supported. However, a lot of details are still missing, and this patches provides a framework to easily handle rendering issues down to the glyph level of certain fonts. Note that ClearType support is not completely implemented! In particular, full support for the options `compatible_widths', `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode instruction) is missing. * src/truetype/ttsubpix.c: New file, providing code to handle `tweaks', this is, rules for certain glyphs in certain fonts (including wildcards) which need a special treatment. * src/truetype/ttsubpix.h: New file, holding the tweaking rules. * include/freetype/config/ftoption.h, src/devel/ftoption.h (TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro. * include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID, FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros. * src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include `ttsubpix.c'. * src/truetype/ttgload.c: Include `ttsubpix.h'. [All changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.] (tt_get_metrics): Set tweak flags. (TT_Hint_Glyph): Call `FT_Outline_EmboldenXY' if necessary. (TT_Process_Simple_Glyph): Compensate emboldening if necessary. (compute_glyph_metrics): Handle `compatible widths' option. (tt_loader_init): Handle ClearType GETINFO information bits. * src/truetype/rules.mk (TT_DRC_SRC): Updated. * src/truetype/ttinterp.c: Include `ttsubpix.h'. [Where necessary, changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.] (Direct_Move, Direct_Move_X): Extended. (Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid, Round_Up_To_Grid, Round_To_Double_Grid, Round_Super, Round_Super_45, SetSuperRound): Add parameter to handle the number of grid lines per pixel. (SET_SuperRound, ROUND_None, CUR_Func_round): Updated. (DO_SROUND, DOS45ROUND, DO_ODD, DO_EVEN): Updated. (DO_ROUND, DO_NROUND): Updated. (DO_RS): Take care of `Typeman' bytecode patterns. (Ins_FDEF): Add some debugging code. Commented out. (Ins_ENDF): Restore state. (Ins_CALL, Ins_LOOPCALL): Handle inline delta functions. (Ins_MD): Handle `Vacuform' rounds.

(Ins_GETINFO): Handle new ClearType bits. (TT_RunIns): Handle tweaks. * src/truetype/ttinterp.h: Updated. (SPH_TweakRule, SPH_ScaleRule): New structures for tweaks.
