7962a15d	2015-09-14T00:38:26	[type1] Fix another potential buffer overflow (#45955). * src/type1/t1parse (T1_Get_Private_Dict): Assure that check for `eexec' doesn't exceed `limit'.
3df92aa0	2015-09-13T09:21:52	[winfonts] Check alignment shift count for resource data (#45938). * src/winfonts/winfnt.c (fnt_face_get_dll_font): Implement it.
e3058617	2015-09-13T08:41:43	[type1] Fix potential buffer overflow (#45923). * src/type1/t1parse.c (T1_Get_Private_Dict): Assure `cur' doesn't point to end of file buffer.
e40e8b33	2015-09-13T08:05:50	[gzip] Fix access of small compressed files (#45937). * src/gzip/ftgzip.c (ft_gzip_stream_close): Avoid memory leak. (ft_gzip_get_uncompressed_file): Correct byte order while reading unsigned long value. Without this change, the whole optimization of accessing small files in `FT_Stream_OpenGzip' is never executed! As a consequence, access to PCF files in general (which are normally small files) should be much improved now as originally intended.
db5a4a9a	2015-09-12T08:32:55	[psaux] Fix potential buffer overflow (#45922). * src/psaux/psobjs.c (ps_parser_skip_PS_token): If a token is enclosed in balanced expressions, ensure that the cursor position doesn't get larger than the current limit.
19b82cfb	2015-09-11T20:25:32	[base] Avoid crash while tracing `load_mac_face'. Reported in Savannah bug #45919. * src/base/ftobjs.c (load_mac_face): Honour FT_OPEN_MEMORY while tracing.
23423bc6	2015-09-11T08:28:27	[type42] Fix endless loop (#45920). * src/type42/t42parse.c (t42_parse_encoding): Synchronize with type1's `parse_encoding'.
e5a27a75	2015-09-10T07:44:11	[docmaker] Allow `-' in bold and italic markup. * src/tools/docmaker/sources.py (re_italic, re_bold): Adjust accordingly.
09948e42	2015-09-09T21:30:15	* src/base/ftcalc.c (FT_RoundFix): Improve.
822acb02	2015-09-09T07:59:10	* src/base/ftcalc.c (FT_CeilFix, FT_FloorFix): Normalize. This commit makes the functions behave as expected, this is, rounding towards plus or minus infinity.
b002f688	2015-09-07T13:47:36	* src/smooth/ftgrays.c (gray_render_line): Simplify clipping.
5a6dc872	2015-09-04T23:14:46	[raster,smooth] Microoptimizations. * src/raster/ftraster.c (Insert_Y_Turn, Finalize_Profile_Table, Beziier_Up, ): Use do-while loops. * src/smooth/ftgrays.c (gray_render_scanline, gray_render_line, gray_convert_glyph): Ditto.
a9f6f04e	2015-09-04T22:28:13	[autofit] Missing piece.
d3cba0ed	2015-09-04T10:28:53	[autofit] Redesign code ranges (2/2). This commit adds two fallback scripts (`latb', `latp') and implements support for the no-base character ranges introduced in the previous commit. * src/autofit/aftypes.h (AF_ScriptClassRec): Add `script_uni_nobase_ranges' field. (AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/afscript.h, src/autofit/afstyles.h: Add `latb' and `latp' fallback scripts. * src/autofit/afblue.dat: Add blue zones for Latin subscript and superscript fallback scripts. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afglobal.h (AF_NOBASE): New style flag for no-base characters. (AF_STYLE_MASK): Updated. * src/autofit/afglobal.c (SCRIPT): Updated. (af_face_globals_compute_style_coverage): Handle new style flag. * src/autofit/aflatin.c (af_latin_hints_apply): Handle new style flag. * src/autofit/afranges.h (SCRIPT): Use it to export no-base ranges.
696b7126	2015-09-04T10:10:59	[autofit] Redesign code ranges (1/2). This patch introduces auxiliary code ranges that identify no-base characters; they refer to glyphs of a script that should be hinted without alignments to blue zones (mostly diacritics). It also splits off ranges for fallback scripts that handle subscript and superscript characters not covered by OpenType features. For example, this greatly helps improve the hinting of various phonetic alphabets, which contain a large amount characters that look like superscript glyphs. Finally, code ranges are updated to Unicode 8.0, and enclosed characters are removed in general since they normally look better if they stay unhinted. * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode 8.0. Split off superscript-like and subscript-like glyphs into... (af_latb_uniranges, af_latp_uniranges): ... these two new arrays. (af_xxxx_nobase_uniranges): New arrays that hold no-base characters of the corresponding character ranges.
8cbbcf6b	2015-09-03T06:47:30	[autofit] Pass glyph index to hinting function. No functionality change yet. * src/autofit/aftypes.h (AF_WritingSystem_ApplyHintsFunc): Pass glyph index. * src/autofit/afcjk.c, src/autofit/afcjk.h (af_cjk_hints_apply), src/autofit/afdummy.c (af_dummy_hints_apply), src/autofit/afindic.c (af_indic_hints_apply), src/autofit/aflatin.c (af_latin_hints_apply), src/autofit/aflatin2.c (af_latin2_hints_apply), src/autofit/afloader.c (af_loader_load_g): Updated.
40103a3a	2015-08-31T08:51:52	[autofit] Code clean-up. * src/autofit/afglobal.h (AF_STYLE_MASK): New macro. (AF_STYLE_UNASSIGNED): Use AF_STYLE_MASK for definition. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): Updated.
87c81f04	2015-08-30T10:35:21	[autofit] Make glyph style array use 16bit values. * include/freetype/ftautoh.h (FT_Prop_GlyphToScriptMap): Use `FT_UShort' for `map' field. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage, af_face_globals_new), src/autofit/hbshim.c, src/autofit/hbshim.h (af_get_coverage): Use FT_UShort for `glyph_styles' array. * src/autofit/afglobal.h (AF_STYLE_UNASSIGNED, AF_DIGIT): Extend to 16 bits. (AF_FaceGlobalsRec): Use `FT_UShort' for `glyph_styles' field.
09635264	2015-08-31T23:14:46	Minor.
6ec0434e	2015-08-30T22:50:48	Minor refactoring.
78b01403	2015-08-25T07:23:01	[base] Improve kerning tracing and documentation. * src/base/ftobjs.c (FT_Get_Kerning): Emit tracing message if scaled-down kerning values differ.
55fed89e	2015-08-24T06:00:49	Remove obsolete comment. Found by Akira Kakuto <kakuto@fuk.kindai.ac.jp>.
91d59169	2015-08-18T06:04:36	[raster] Remove last remnants of `raster5' driver. * src/raster/ftrend1.h (ft_raster5_renderer_class): Removed. * src/raster/rastpic.c, src/raster/rastpic.h (ft_raster5_renderer_class_pic_init, ft_raster5_renderer_class_pic_free): Removed.

ae258aa0	2015-08-14T23:23:18	[truetype] Clean up. * src/truetype/ttgload.c (TT_Process_Composite_Component): Use `FT_Outline_Transform' and `FT_Outline_Translate'. (translate_array): Dropped.
14d6b5d7	2015-08-13T15:22:17	[truetype] Introduce named instance access to GX fonts. For functions querying a face, bits 16-30 of the face index can hold the named instance index if we have a GX font. The indices start with value 1; value 0 indicates font access without GX variation data. * include/freetype/freetype.h (FT_FaceRec): Update documentation. * include/freetype/internal/sfnt.h: Ditto. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Get number of named instances and do argument checks. (sfnt_load_face): Updated. * src/truetype/ttobjs.c (tt_face_init) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Use named instance, overwriting the style name. * src/base/ftobjs.c (open_face_from_buffer, open_face_PS_from_sfnt_stream): Updated. * src/bdf/bdfdrivr.c (BDF_Face_Init): Updated. * src/cff/cffload.c (cff_font_load): Updated. * src/cff/cffobjs.c (cff_face_init): Make function exit early for pure CFF fonts if `font_index < 0'. Updated. * src/cid/cidobjs.c (cid_face_init): Updated. * src/pcf/pcfdrivr.c (PCF_Face_Init): Updated. * src/pfr/pfrobjs.c (pfr_face_init): Updated. * src/type1/t1objs.c (T1_Face_Init): Updated. * src/type42/t42objs.c (T42_Face_Init): Updated. * src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init): Updated. * docs/CHANGES: Updated.
4afc0a54	2015-08-12T23:51:02	Comment typos.
4a466865	2015-08-12T23:45:40	[type1,cff,cid] Streamline font matrix application. * src/type1/t1gload.c (T1_Load_Glyph): Directly modify advances only if font matrix is not trivial. * src/cff/cffgload.c (cff_slot_load): Ditto. * sff/cid/cidgload.c (cid_slot_load_glyph): Ditto for advances and the entire outline.
a37da21a	2015-08-10T23:05:02	[type1,cid,type42] Minor improvements. * src/type1/t1load.c (t1_parse_font_matrix): Scale units per EM only when necessary. Refresh comments. * src/cid/cidload.c (cid_parse_font_matrix): Ditto. * src/type42/t42parse.c (t42_parse_font_matrix): Refresh comments.
bd75a517	2015-08-08T08:39:45	[type42] Fix glyph access. This is a severe bug: We've missed one level of indirection, as described in the Type 42 specification. As a result, ftview sometimes showed incorrect glyphs for given glyph names, and even displayed `error 0x0006' (invalid argument!) in case the number of glyph indices differed between the Type 42 font and the embedded TTF. Apparently, noone ever noticed it; this shows how much Type 42 fonts are in use... * src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index to embedded TTF's glyph index.
e5f44693	2015-08-08T07:45:03	[type42] Minor clean-up. * src/type42/t42parse.c (t42_parse_font_matrix): Remove unused variable.
fd70512e	2015-08-06T21:49:08	[type42] Parse FontMatrix according to specifications. * src/type42/t42parse.c (t42_parse_font_matrix): Type 42 FontMatrix does not need scaling by 1000. Units_per_EM are taken from the embedded TrueType.
ff406e2e	2015-08-06T07:34:50	[autofit] Improve Arabic hinting. Problem reported by Titus Nemeth <tn@tntypography.eu> (by using ttfautohint). * src/autofit/afblue.dat: Add neutral blue zone for the tatweel character. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
98e8e999	2015-08-06T00:06:14	[truetype] Clean up types. * src/truetype/ttobjs.c (TT_Size): Move declaration from here. * include/freetype/internal/tttypes.h (TT_Size): ... to here. (TT_LoaderRec): Switch to appropriate types for `face' and `size'. * src/truetype/ttgload.c: Remove corresponding type casts. * src/truetype/ttsubpix.c: Ditto.
15e2a4f7	2015-08-05T21:53:50	[autofit] Improve recognition of flat vs. rounded segments. Lower the flatness threshold from upem/8 to upem/14, making the auto-hinter accept shorter elements. Synchronize flat/round stem selection algorithm with blue zone code. * src/autofit/aflatin.c (FLAT_THRESHOLD): New macro. (af_latin_metrics_init_blues): Use it. (af_latin_hints_compute_segments): Collect information on maximum and minimum coordinates of `on' points; use this to add a constraint for the flat/round decision similar to `af_latin_metrics_init_blues'.
eb22ef26	2015-08-04T06:50:04	Another left-shift bug (#45681). * src/base/ftobjs.c (IsMacBinary): Only accept positive values for `dlen'.
7e6c321a	2015-08-03T23:26:13	[base] Fix `ft_corner_orientation'. Remove casting from `FT_Long' to `FT_Int' that might change the sign of the return value and make it faster too. * src/base/ftcalc.c (ft_corner_orientation): On 32-bit systems, stay with 32-bit arithmetic when safe. Use plain math on 64-bit systems. * src/pshinter/pshalgo.c: Remove old unused code.
8dfc7601	2015-08-03T12:23:30	* src/truetype/ttgload.c (load_truetype_glyph) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Fix crash for composite glyphs having a depth greater than 1.
ca6a5cf4	2015-08-03T08:51:18	Fix typo in clang bug from 2015-07-31 (#45678). * src/base/ftrfork.c (FT_Raccess_Get_HeaderInfo): Fix inequality.

70e9d815	2015-08-02T09:42:12	Fix more invalid left-shifts. * src/pfr/pfrgload.c (pfr_glyph_load_compound): Use multiplication, not left-shift. * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar, tt_face_vary_cvt, TT_Vary_Apply_Glyph_Deltas): Use multiplication, not left-shift.
6343ba22	2015-08-01T07:53:48	Fix some bugs found by clang's `-fsanitize=undefined' (#45661). * src/base/ftrfork.c (FT_Raccess_Get_HeaderInfo): Only accept positive values from header. Check overflow. * src/base/ftoutln.c (SCALED): Correctly handle left-shift of negative values. * src/bdf/bdf.h (_bdf_glyph_modified, _bdf_set_glyph_modified, _bdf_clear_glyph_modified): Use unsigned long constant. * src/bdf/bdfdrivr.c (BDF_Size_Select, BDF_Glyph_Load): Don't left-shift values that can be negative. * src/pcf/pcfdrivr.c (PCF_Size_Select, PCF_Glyph_Load): Don't left-shift values that can be negative. * src/raster/ftraster.c (SCALED): Correctly handle left-shift of negative values. * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Don't left-shift values that can be negative. * src/truetype/ttgload.c (TT_Load_Composite_Glyph, compute_glyph_metrics, load_sbit_image): Don't left-shift values that can be negative.
5d1b8ab4	2015-07-31T21:49:07	Define FT_LONG_MAX. * include/freetype/config/ftstdlib.h (FT_LONG_MAX): New macro. * src/cff/cf2arrst.c (cf2_arrstack_setNumElements): Use it.

b650dfbb	2015-07-26T21:08:34	[cff] Don't use `hmtx' table for LSB (#45520). * src/cff/cffgload.c (cff_slot_load): Use `htmx' table for advance width only. Bug introduced 2015-04-10.
f9be567f	2015-07-09T15:10:31	Better support of user-supplied C++ namespaces. See http://lists.nongnu.org/archive/html/freetype-devel/2015-07/msg00008.html for a rationale. * src/autofit/afpic.h, src/base/basepic.h, src/cff/cffpic.h, src/pshinter/pshpic.h, src/psnames/pspic.h, src/raster/rastpic.h, src/sfnt/sfntpic.h, src/smooth/ftspic.h, src/truetype/ttpic.h (FT_BEGIN_HEADER, FT_END_HEADER): Move macro calls to not enclose header files that contain FT_{BEGIN,END}_HEADER macros by themselves. * src/autofit/aftypes.h [FT_DEBUG_AUTOFIT]: Include FT_CONFIG_STANDARD_LIBRARY_H earlier. * src/truetype/ttpic.h: Include FT_INTERNL_PIC_H.
1cdac10d	2015-07-07T14:04:44	[sfnt] Make `tt_face_get_name' member of the SFNT interface. * include/freetype/internal/sfnt.h (TT_Get_Name_Func): New prototype. (SFNT_Interface, FT_DEFINE_SFNT_INTERFACE): New member `get_name'. * src/sfnt/sfdriver.c (sfnt_interface): Updated. * src/sfnt/sfobjs.c (tt_face_get_name): Tag it with `LOCAL_DEF'. * src/sfnt/sfobjs.h: Add prototype for it.

5aaabb44	2015-06-29T22:46:54	[truetype] Speed up bytecode interpreter. * src/truetype/ttinterp.c (Normalize): Use `FT_Vector_NormLen'.
9ef02bd4	2015-06-29T22:39:10	[base] Speed up emboldening. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Use `FT_Vector_NormLen'.
884e4e67	2015-06-29T22:32:05	[base] Implement fast vector normalization. The function uses Newton's iterations instead of dividing vector components by its length, which needs a square root. This is, literally, a bit less accurate but a lot faster. * src/base/ftcalc.c (FT_Vector_NormLen): New function.
802f6a9a	2015-06-27T07:12:42	* src/tools/docmaker/utils.py (check_output): Add missing `\n'.
392cf22f	2015-06-25T13:04:57	Another adjustment to header locations. This change is a result of a discussion thread on freetype-devel http://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html Re-introduce the `freetype2' subdirectory for all FreeType header files after installation, and rename the `freetype2' subdirectory in the git repository to `freetype'. * include/freetype2: Renamed to... * include/freetype: This. * CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS): Updated. Update creation of `ftconfig.h'. Install generated `ftconfig.h'. * Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated. * builds/amiga/include/config/ftconfig.h, builds/freetype.mk (PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work), builds/unix/freetype2.in: Updated. * builds/unix/freetype-config.in: Updated. * builds/unix/configure.raw: Don't check for `rmdir'. * builds/unix/unix-def.in (DELDIR): Use `rm -rf', which is portable according to the autoconf info manual. * builds/unix/install.mk (install, uninstall, distclean_project_unix): Update and simplify. * builds/wince/, builds/windows/: Updated. * devel/ft2build.h, include/ft2build.h: Updated. * include/freetype2/config/ftheader.h, include/freetype2/internal/ftserv.h, include/freetype2/internal/internal.h: Update all header file macros. * src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated. * docs/*: Updated.
41bfbadc	2015-06-24T23:57:19	* src/bdf/bdflib.c (_bdf_parse_start): Disallow 0 bpp.
4308b7b1	2015-06-24T23:31:17	* src/bdf/bdflib.c (_bdf_parse_start): Simplify bpp parsing.
5931268e	2015-06-23T09:24:48	s/TYPEOF/FT_TYPEOF/ (#45376). * builds/unix/ftconfig.in, builds/vms/ftconfig.in, include/freetype2/config/ftconfig.h, include/freetype2/internal/ftobjs.h, src/autofit/afwarp.h: Do it.
8502c98b	2015-06-22T06:35:23	Fix Savannah bug #45097. We no longer `pollute' the namespace of possible header file names; instead we move `ft2build.h' up by one level so that it gets installed in the default include directory (e.g., /usr/local/include). After this commit, only `ft2build.h' stays in the compiler's include path. No visible changes for the user who follows the standard FreeType header inclusion rules. * include/: Move to ... include/freetype2/: This directory, except `ft2build.h'. CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS), Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated. * builds/amiga/include/config/ftconfig.h, builds/freetype.mk (PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work), builds/unix/install.mk (install, uninstall), builds/unix/freetype2.in: Updated. * builds/unix/freetype-config.in: Updated. Emit -I directory only if it is not `/usr/include'. * builds/wince/, builds/windows/: Updated. * devel/ft2build.h, include/ft2build.h: Updated. * include/freetype2/config/ftheader.h, include/freetype2/internal/ftserv.h, include/freetype2/internal/internal.h: Update all header file macros. * src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated. * docs/*: Updated.
31d97df9	2015-06-21T19:12:12	Make Jam support work again. This is just very basic stuff and just a little bit tested on GNU/Linux only. I won't delve into this since I'm not a Jam user. * Jamfile: Call `HDRMACRO' for `ftserv.h' also. (DEFINES): Replace with... (CCFLAGS): ... this. * src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is already handled in the top-level Jamfile. * src/autofit/Jamfile (DEFINES): Replace with... (CCFLAGS): ... this. (_sources): Add missing files. * src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no longer contains macro header definitions. * src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile, src/truetype/Jamfile (_sources): Add missing files.
1a147ac0	2015-06-16T10:20:07	Fix Savannah bug #45326. * src/sfnt/sfntpic.h (SFNT_SERVICES_GET): Remove duplicate definitions.

472119ac	2015-06-06T05:45:17	Fix Savannah bug #45260. * src/pfr/pfrdrivr.c (pfr_get_kerning): Fix typo.
75534a04	2015-06-03T00:54:09	[truetype] Fix memory leak. Problem reported by Grissiom <chaos.proton@gmail.com>; in http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html there is an example code to trigger the bug. * src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size' data before allocating again. Bug most probably introduced four years ago in version 2.4.3.
d1ade6d1	2015-06-02T11:44:52	[raster] Add more tracing. * src/raster/ftraster.c (FT_TRACE7) [_STANDALONE_]: Define. (Vertical_Sweep_Span, Vertical_Sweep_Drop, Horizontal_Sweep_Span, Horizontal_Sweep_Drop, Render_Glyph): Add tracing calls.
54d04286	2015-06-01T12:12:06	[truetype] While tracing opcodes, show code position and stack. * src/truetype/ttinterp.c: Change all existing TRACE7 calls to TRACE6. (opcode_name): Add string lengths. (TT_RunIns): Implement display of code position and stack.
e9df4e47	2015-05-31T12:21:34	[truetype] In GX, make private point numbers work correctly. This is completely missing in Apple's documentation: If a `gvar' tuple uses private point numbers (this is, deltas are specified for some points only), the uncovered points must be interpolated for this tuple similar to the IUP bytecode instruction. Examples that need this functionality are glyphs `Oslash' and `Q' in Skia.ttf. * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate, tt_handle_deltas): New functions. (TT_Vary_Get_Glyph_Deltas): Renamed to... (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the points and does no longer return an array of deltas. Add tracing information. Call `tt_handle_deltas' to interpolate missing deltas. Also fix a minor memory leak in case of error. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Updated.
9845c1d4	2015-05-31T11:57:31	[truetype] In GX, make intermediate tuplets work at extrema. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition.
cdee7d14	2015-05-31T11:54:42	[truetype] Add tracing information to GX code. * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar, ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend, TT_Set_Var_Design, tt_face_vary_cvt): Do it.
a678560d	2015-05-28T17:31:15	Minor.

a5e1f6f3	2015-05-24T23:29:23	[truetype] Fix commit from 2015-05-22. * src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'. Problem reported by Nikolaus Waxweiler <madigens@gmail.com>.
7f099482	2015-05-24T09:50:24	[truetype] Fix return values of GETINFO bytecode instruction. * src/truetype/ttinterp.h (TT_ExecContextRec): New fields `vertical_lcd' and `gray_cleartype'. * src/truetype/ttgload.c (tt_loader_init): Initialize new fields. Change `symmetrical smoothing' to TRUE, since FreeType produces exactly this. * src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit values for symmetrical smoothing, namely 11/18. Handle bits for vertical LCD subpixels (8/15) and Gray ClearType (12/19).
bb435da2	2015-05-23T07:21:25	[truetype] Minor. * src/truetype/ttinterp.h (TT_ExecContext): s/subpixel/subpixel_hinting. * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
c61cad86	2015-05-22T22:02:15	[truetype] Support selector index 3 of the INSTCTRL instruction. This flag activates `native ClearType hinting', disabling backwards compatibility mode as described in Greg Hitchcocks whitepaper. In other words, it enables unrestricted functionality of all TrueType instructions in ClearType. * src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks' unconditionally. (tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of `GS.instruct_control' is active. * src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3. (Ins_GETINFO): Updated. * docs/CHANGES: Document it.
790b8dfb	2015-05-20T12:33:40	[truetype] Minor.
0a6b6ff7	2015-05-17T22:54:48	[truetype] Fix loading of composite glyphs. * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the ARGS_ARE_XY_VALUES flag is not set, handle argument values as unsigned. I trust `ttx' (which has exactly such code) that it does the right thing here... The reason that noone has ever noticed this bug is probably the fact that point-aligned subglyphs are rare, as are subglyphs with a number of points in the range [128;255], which is quite large (or even in the range [32768;65535], which is extremely unlikely).
a87fb8cc	2015-05-12T07:27:35	[cff] Make the `curveto' operators more tolerant. src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes `vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate, pulling values off the stack until the stack is exhausted. Implicitly the stack must be a multiple (or for subtly different behaviour) a multiple plus a specific number of extra values deep. If that's not the case, enforce it (as the old code did).
d65bf72c	2015-05-12T07:16:46	[cff] fix incremental interface with new cff code. * src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental interface to retrieve glyph data for a SEAC, it be left to the incremental interface callback to apply the encoding to raw character index (as it was in the previous code).
40914952	2015-04-29T21:57:30	[autofit] Speed up IUP. * src/autofit/afhints.c (af_iup_interp): Separate trivial snapping to the same position from true interpolation, use `scale' to reduce divisions.
3cc076da	2015-04-28T09:16:27	[cff] Use `name' table for PS name if we have a SFNT-CFF. This follows the OpenType 1.7 specification. See http://tug.org/pipermail/tex-live/2015-April/036634.html for a discussion. * src/cff/cffdrivr.c (cff_get_ps_name): Use the `sfnt' service if we have an SFNT.
40623a1f	2015-04-27T22:27:00	[truetype] Speed up IUP. * src/truetype/ttinterp.c (_iup_worker_interpolate): Separate trivial snapping to the same position from true interpolation.
b6c511d9	2015-04-24T00:10:40	* src/base/ftoutln.c: Minor.
14df6b1a	2015-04-22T11:14:35	[autofit] By default, enable warping code but switch off warping. Suggested by Behdad. * include/config/ftoption.h: Define AF_CONFIG_OPTION_USE_WARPER. * src/autofit/afmodule.c (af_autofitter_init): Initialize `warping' with `false'.
12661a5a	2015-04-21T07:13:59	[autofit] Introduce `warping' property. This code replaces the debugging hook from the previous commit with a better, more generic solution. * include/ftautoh.h: Document it. * src/autofit/afmodule.h (AF_ModuleRec) [AF_CONFIG_OPTION_USE_WARPER]: Add `warping' field. * src/autofit/afmodule.c (_af_debug_disable_warper): Remove. (af_property_set, af_property_get, af_autofitter_init) [AF_CONFIG_OPTION_USE_WARPER]: Handle `warping' option. * src/autofit/afhints.h (AF_HINTS_DO_WARP): Remove use of the no longer existing `_af_debug_disable_warper'. * src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c (af_latin_hints_init), src/autofit/aflatin2.c (af_latin2_hints_init) [AF_CONFIG_OPTION_USE_WARPER]: Add `AF_SCALER_FLAG_NO_WARPER' to the scaler flags if warping is off. * src/autofit/aftypes.h: Updated.
58f48f0d	2015-04-16T20:11:49	[autofit] Add debugging hook to disable warper. * src/autofit/afmodule.c (_af_debug_disable_warper) [FT_DEBUG_AUTOFIT]: New global variable. * src/autofit/aftypes.h: Updated. (AF_SCALER_FLAG_NO_WARPER): New macro (not actively used yet). * src/autofit/afhints.h (AF_HINTS_DO_WARP): New macro. * src/autofi/aflatin.c (af_latin_hints_apply) [AF_CONFIG_OPTION_USE_WARPER]: Use `AF_HINTS_DO_WARP' to control use of warper. * src/autofit/afcjk.c (af_cjk_hints_init, af_cjk_hints_apply) [AF_CONFIG_OPTION_USE_WARPER]: Synchronize with `aflatin.c'. * src/autofit/aflatin2.c (af_latin2_hints_apply) [AF_CONFIG_OPTION_USE_WARPER]: Synchronize with `aflatin.c'.

[autofit] Redesign code ranges (2/2). This commit adds two fallback scripts (`latb', `latp') and implements support for the no-base character ranges introduced in the previous commit. * src/autofit/aftypes.h (AF_ScriptClassRec): Add `script_uni_nobase_ranges' field. (AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/afscript.h, src/autofit/afstyles.h: Add `latb' and `latp' fallback scripts. * src/autofit/afblue.dat: Add blue zones for Latin subscript and superscript fallback scripts. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afglobal.h (AF_NOBASE): New style flag for no-base characters.

[autofit] Redesign code ranges (1/2). This patch introduces auxiliary code ranges that identify no-base characters; they refer to glyphs of a script that should be hinted without alignments to blue zones (mostly diacritics). It also splits off ranges for fallback scripts that handle subscript and superscript characters not covered by OpenType features. For example, this greatly helps improve the hinting of various phonetic alphabets, which contain a large amount characters that look like superscript glyphs. Finally, code ranges are updated to Unicode 8.0, and enclosed characters are removed in general since they normally look better if they stay unhinted. * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode 8.0. Split off superscript-like and subscript-like glyphs into... (af_latb_uniranges, af_latp_uniranges): ... these two new arrays. (af_xxxx_nobase_uniranges): New arrays that hold no-base characters of the corresponding character ranges.

[type42] Fix glyph access. This is a severe bug: We've missed one level of indirection, as described in the Type 42 specification. As a result, ftview sometimes showed incorrect glyphs for given glyph names, and even displayed `error 0x0006' (invalid argument!) in case the number of glyph indices differed between the Type 42 font and the embedded TTF. Apparently, noone ever noticed it; this shows how much Type 42 fonts are in use... * src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index to embedded TTF's glyph index.

Fix Savannah bug #45097. We no longer `pollute' the namespace of possible header file names; instead we move `ft2build.h' up by one level so that it gets installed in the default include directory (e.g., /usr/local/include).

[truetype] In GX, make private point numbers work correctly. This is completely missing in Apple's documentation: If a `gvar' tuple uses private point numbers (this is, deltas are specified for some points only), the uncovered points must be interpolated for this tuple similar to the IUP bytecode instruction. Examples that need this functionality are glyphs `Oslash' and `Q' in Skia.ttf. * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate, tt_handle_deltas): New functions. (TT_Vary_Get_Glyph_Deltas): Renamed to... (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the points and does no longer return an array of deltas. Add tracing information. Call `tt_handle_deltas' to interpolate missing deltas. Also fix a minor memory leak in case of error. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Updated.

[truetype] Fix loading of composite glyphs. * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the ARGS_ARE_XY_VALUES flag is not set, handle argument values as unsigned. I trust `ttx' (which has exactly such code) that it does the right thing here... The reason that noone has ever noticed this bug is probably the fact that point-aligned subglyphs are rare, as are subglyphs with a number of points in the range [128;255], which is quite large (or even in the range [32768;65535], which is extremely unlikely).

[cff] Make the `*curveto' operators more tolerant. * src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes `vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate, pulling values off the stack until the stack is exhausted. Implicitly the stack must be a multiple (or for subtly different behaviour) a multiple plus a specific number of extra values deep. If that's not the case, enforce it (as the old code did).
