2015-10-12 Werner Lemberg [unix] Make MKDIR_P actually work. * builds/unix/configure.raw: Fix underquoting of `INSTALL' and `MKDIR_P'. Problem reported by Dan Liddell . 2015-10-11 Werner Lemberg [sfnt] Improve extraction of number of named instances. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Check number of instances against `fvar' table size. 2015-10-10 Alexei Podtelezhnikov * src/base/ftoutln.c (FT_Outline_Get_Orientation): Fix overflow (#46149). 2015-10-10 Werner Lemberg [sfnt] Fix infinite loops with broken cmaps (#46167). * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next): Take care of border conditions (i.e., if the loops exit naturally). 2015-10-10 Werner Lemberg [truetype] More sanity tests for GX handling. These tests should mainly help avoid unnecessarily large memory allocations in case of malformed fonts. * src/truetype/ttgxvar.c (ft_var_readpackedpoints, ft_var_readpackeddeltas): Check number of points against stream size. (ft_var_load_avar): Check `pairCount' against table length. (ft_var_load_gvar): Check `globalCoordCount' and `glyphCount' against table length. (tt_face_vary_cvt): Check `tupleCount' and `offsetToData'. Fix trace. (TT_Vary_Apply_Glyph_Deltas): Fix trace. Free `sharedpoints' to avoid memory leak. 2015-10-10 Werner Lemberg [truetype] Better protection against malformed GX data (#46166). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Correctly handle empty `localpoints' array. 2015-10-10 Werner Lemberg * src/pcf/pcfread.c (pcf_read_TOC): Check stream size (#46162). 2015-10-09 Werner Lemberg * src/gzip/ftgzip.c (FT_Stream_OpenGzip): Use real stream size. 2015-10-08 Werner Lemberg [pcf] Protect against invalid number of TOC entries (#46159). * src/pcf/pcfread.c (pcf_read_TOC): Check number of TOC entries against size of data stream. 2015-10-08 Werner Lemberg [type42] Protect against invalid number of glyphs (#46159). * src/type42/t42parse.c (t42_parse_charstrings): Check number of `CharStrings' dictionary entries against size of data stream. 2015-10-08 Werner Lemberg [sfnt] Fix some signed overflows (#46149). * src/sfnt/ttsbit.c (tt_face_load_strike_metrics) : Use `FT_MulDiv'. 2015-10-08 Werner Lemberg [type1] Protect against invalid number of subroutines (#46150). * src/type1/t1load.c (parse_subrs): Check number of `Subrs' dictionary entries against size of data stream. 2015-10-07 Kostya Serebryany [ftfuzzer] Add support for LLVM's LibFuzzer. * src/tools/ftfuzzer/ftfuzzer.cc, src/tools/runinput.cc: New files. 2015-10-06 Alexei Podtelezhnikov [smooth] Faster alternative line renderer. This implementation renders the entire line segment at once without subdividing it into scanlines. The main speed improvement comes from reducing the number of divisions to just two per line segment, which is a bare minimum to calculate cell coverage in a smooth rasterizer. Notably, the progression from cell to cell does not itself require any divisions at all. The speed improvement is more noticeable at larger sizes. * src/smooth/ftgrays.c (gray_render_line): New implementation. 2015-10-06 Werner Lemberg [cff] Return correct PS names from pure CFF (#46130). * src/cff/cffdrivr.c (cff_get_ps_name): Use SFNT service only for SFNT. 2015-10-04 Werner Lemberg [base] Replace left shifts with multiplication (#46118). * src/base/ftglyph.c (ft_bitmap_glyph_bbox, FT_Get_Glyph): Do it. 2015-10-04 Werner Lemberg * Version 2.6.1 released. ========================= Tag sources with `VER-2-6-1'. * docs/VERSION.DLL: Update documentation and bump version number to 2.6.1. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, 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/2.6/2.6.1/, s/26/261/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 18:1:12. * CMakeLists.txt (VERSION_PATCH): Set to 1. * src/autofit/afmodule.c [AF_DEBUG_AUTOFIT]: Ensure C linking for dumping functions. 2015-10-04 Werner Lemberg [bzip2, gzip] Avoid access of unitialized memory (#46109). * src/bzip2/ftbzip2.c (ft_bzip2_file_fill_input), src/gzip/ftgzip.c (ft_gzip_file_fill_input): In case of an error, adjust the limit to avoid copying uninitialized memory. 2015-10-03 Werner Lemberg [bzip2, gzip] Avoid access of unitialized memory (#46109). * src/bzip2/ftbzip2.c (ft_bzip2_file_fill_output), src/gzip/ftgzip.c (ft_gzip_file_fill_output): In case of an error, adjust the limit to avoid copying uninitialized memory. 2015-10-01 Alexei Podtelezhnikov [smooth] Clean up worker. * src/smooth/ftgrays.c (gray_TWorker): Remove never used fields. 2015-10-01 Werner Lemberg [sfnt] Make `tt_cmap4_char_map_linear' more robust (#46078). * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Take care of border conditions (i.e., if the loop exits naturally). 2015-10-01 Werner Lemberg * src/autofit/afranges.c (af_deva_nonbase_uniranges): Fix ranges. They should be a subset of `af_deva_uniranges'. 2015-10-01 Werner Lemberg [sfnt] Make `tt_cmap4_char_map_linear' faster (#46078). * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Use inner loop to reject too large glyph indices. 2015-09-30 Alexei Podtelezhnikov [smooth] Clean up worker. * src/smooth/ftgrays.c (gray_TWorker): Remove lightly used `last_ey'.

Suggested by Hin-Tak Leung. * src/bzip2/ftbzip2.c (ft_bzip2_stream_io), src/gzip/ftgzip.c (ft_gzip_stream_io), src/lzw/ftlzw.c (ft_lzw_stream_io): Do it. 2015-09-26 Hin-Tak Leung Add new FT_LOAD_COMPUTE_METRICS load flag. * include/freetype/freetype.h (FT_LOAD_COMPUTE_METRICS): New macro. * src/truetype/ttgload.c (compute_glyph_metrics): Usage. 2015-09-26 Werner Lemberg * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add cast. 2015-09-25 Werner Lemberg [type1] Protect against invalid number of glyphs (#46029). * src/type1/t1load.c (parse_charstrings): Check number of `CharStrings' dictionary entries against size of data stream. 2015-09-23 Werner Lemberg [sfnt] Better checks for invalid cmaps (2/2) (#46019). While the current code in `FT_Get_Next_Char' correctly rejects out-of-bounds glyph indices, it can be extremely slow for malformed cmaps that use 32bit values. This commit tries to improve that. * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next, tt_cmap12_char_map_binary, tt_cmap13_next, tt_cmap13_char_map_binary): Reject glyph indices larger than or equal to the number of glyphs. 2015-09-23 Werner Lemberg [base, sfnt] Better checks for invalid cmaps (1/2). * src/base/ftobjs.c (FT_Get_Char_Index): Don't return out-of-bounds glyph indices.

(tt_cmap13_char_next): Simplify. 2015-09-21 suzuki toshiya [base] Check too long POST and sfnt resource (#45919). * src/base/ftbase.h (FT_MAC_RFORK_MAX_LEN): Maximum length of the resource fork for Mac OS. Resource forks larger than 16 MB can be written but can't be handled correctly, at least in Carbon routine.

(Mac_Read_sfnt_Resource): Check the declared size of sfnt resource before buffer allocation. * src/base/ftmac.c (read_lwfn, FT_New_Face_From_SFNT): Check the total resource size before buffer allocation. 2015-09-19 Werner Lemberg [sfnt] Improve handling of invalid SFNT table entries (#45987). This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables. Add another tracing message. (tt_face_load_font_dir): Only allocate table array for valid entries as returned by `check_table_dir'. Reject duplicate tables and adjust number of valid tables accordingly. 2015-09-19 Werner Lemberg [pcf] Improve `FT_ABS' fix from 2015-09-17 (#45999). * src/pcf/pcfread.c (pcf_load_font): Do first the cast to FT_Short, then take the absolute value. Also apply FT_ABS to `height'. 2015-09-17 Werner Lemberg [type42] Fix memory leak (#45989). * src/type42/t42parse.c (t42_parse_charstrings): Allow only a single `CharStrings' array. 2015-09-17 Werner Lemberg [psaux] Fix memory leak (#45986). * src/psaux/psobjs.c (ps_parser_load_field) : Free `temp' in case of error. 2015-09-17 Werner Lemberg [psaux] Improve tracing message. * src/psaux/psobjs.c (ps_parser_load_field) : Handle plural correctly. 2015-09-17 Werner Lemberg [pcf] Fix integer overflows (#45985). * src/pcf/pcfread.c (pcf_load_font): Use FT_MulDiv. 2015-09-17 Werner Lemberg [pcf] Use FT_ABS for some property values (#45893). * src/pcf/pcfread.c (pcf_load_font): Take absolute values for AVERAGE_WIDTH, POINT_SIZE, PIXEL_SIZE, RESOLUTION_X, and RESOLUTION_Y. In tracing mode, add warnings. 2015-09-16 Werner Lemberg Minor fixes for some clang warnings. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Cast, possible missing initialization. * src/truetype/ttgload.c (TT_Process_Composite_Component): Cast. 2015-09-15 Werner Lemberg [type1, type42] Fix memory leaks (#45966). * src/type1/t1load.c (parse_blend_axis_types): Handle multiple axis names.

(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. 2015-09-11 Werner Lemberg [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. 2015-09-11 Werner Lemberg [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. 2015-09-11 Werner Lemberg [type42] Fix endless loop (#45920). * src/type42/t42parse.c (t42_parse_encoding): Synchronize with type1's `parse_encoding'. 2015-09-10 Werner Lemberg [docmaker] Allow `-' in bold and italic markup. * src/tools/docmaker/sources.py (re_italic, re_bold): Adjust accordingly. 2015-09-09 Alexei Podtelezhnikov * src/base/ftcalc.c (FT_RoundFix): Improve. 2015-09-09 Wojciech Mamrak * src/base/ftcalc.c (FT_CeilFix, FT_FloorFix): Normalize.

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. 2015-09-04 Werner Lemberg [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.

(translate_array): Dropped. 2015-08-14 Andreas Enge * builds/unix/detect.mk (CONFIG_SHELL): Don't handle it (#44261). 2015-08-13 Werner Lemberg [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.

Refresh comments. * src/cid/cidload.c (cid_parse_font_matrix): Ditto. * src/type42/t42parse.c (t42_parse_font_matrix): Refresh comments. 2015-08-08 Werner Lemberg [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. 2015-08-08 Werner Lemberg [type42] Minor clean-up. * src/type42/t42parse.c (t42_parse_font_matrix): Remove unused variable. 2015-08-06 Alexei Podtelezhnikov [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. 2015-08-06 Werner Lemberg [autofit] Improve Arabic hinting. Problem reported by Titus Nemeth (by using ttfautohint). * src/autofit/afblue.dat: Add neutral blue zone for the tatweel character. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. 2015-08-05 Alexei Podtelezhnikov [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. 2015-08-05 Werner Lemberg [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'. 2015-08-04 Werner Lemberg Another left-shift bug (#45681). * src/base/ftobjs.c (IsMacBinary): Only accept positive values for `dlen'. 2015-08-03 Alexei Podtelezhnikov [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. 2015-08-03 Werner Lemberg * src/truetype/ttgload.c (load_truetype_glyph) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Fix crash for composite glyphs having a depth greater than 1. 2015-08-03 Werner Lemberg Fix typo in clang bug from 2015-07-31 (#45678). * src/base/ftrfork.c (FT_Raccess_Get_HeaderInfo): Fix inequality. 2015-08-02 Werner Lemberg * CMakeLists.txt: Improve shared library support. Based on a patch from John Cary . 2015-08-02 Werner Lemberg * builds/unix/freetype-config.in (enable_shared): Remove. Unused. 2015-08-02 Werner Lemberg 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. 2015-07-31 Werner Lemberg 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. 2015-07-31 Werner Lemberg Define FT_LONG_MAX. * include/freetype/config/ftstdlib.h (FT_LONG_MAX): New macro. * src/cff/cf2arrst.c (cf2_arrstack_setNumElements): Use it. 2015-07-28 Alexei Podtelezhnikov * src/base/ftcalc.c (FT_Vector_NormLen): Clarify. 2015-07-27 Alexei Podtelezhnikov * src/base/ftcalc.c (FT_Vector_NormLen): Explicate type conversions. 2015-07-26 Matthias Clasen [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. 2015-07-09 Werner Lemberg 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. 2015-07-07 Werner Lemberg [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. 2015-06-30 Werner Lemberg Fix some clang compiler warnings. * src/base/ftoutln.c (FT_Outline_EmboldenXY), src/cff/cf2intrp.c (cf2_interpT2CharString), src/truetype/ttgload.c (load_truetype_glyph), src/truetype/ttgxvar.c (tt_handle_deltas), src/truetype/ttinterp.c (Ins_INSTCTRL): Fix signedness issues. 2015-06-29 Alexei Podtelezhnikov [truetype] Speed up bytecode interpreter. * src/truetype/ttinterp.c (Normalize): Use `FT_Vector_NormLen'. 2015-06-29 Alexei Podtelezhnikov [base] Speed up emboldening. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Use `FT_Vector_NormLen'. 2015-06-29 Alexei Podtelezhnikov [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. 2015-06-28 Werner Lemberg * CMakeLists.txt: Always create `ftconfig.h'. For non-UNIX builds, the file stays unmodified. However, it's better to have the main configuration files at the same place regardless of the OS. 2015-06-28 Werner Lemberg * CMakeLists.txt: Improve MSVC support (#43737). 2015-06-28 Werner Lemberg [cmake] Check for libraries and create `ftoption.h'. * builds/FindHarfBuzz.cmake: New file, taken from https://trac.webkit.org/browser/trunk/Source/cmake/FindHarfBuzz.cmake * CMakeLists.Txt: Add path to local cmake modules. Find dependencies for zlib, bzip2, libpng, and harfbuzz. Create `ftoption.h' file. Set up include and linker stuff for libraries. 2015-06-28 Werner Lemberg * CMakeLists.txt: Fix creation of `ftconfig.h'. Check for UNIX header files using `check_include_file'. Set up correct header include directories. 2015-06-28 Werner Lemberg * CMakeLists.txt: Disallow in-source builds. 2015-06-27 Werner Lemberg * src/tools/docmaker/utils.py (check_output): Add missing `\n'. 2015-06-26 Werner Lemberg * CMakeLists.txt: Select platform-dependent `ftdebug.c'. 2015-06-25 Werner Lemberg * CMakeLists.txt: Use cmake functions for generating `ftconfig.h'. Additionally, do this for UNIX only. 2015-06-25 Werner Lemberg * CMakeLists.txt (BASE_SRCS): Use `ftbase.c' and `psnames.c'. 2015-06-25 Werner Lemberg 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. 2015-06-24 Alexei Podtelezhnikov * src/bdf/bdflib.c (_bdf_parse_start): Disallow 0 bpp. 2015-06-24 Alexei Podtelezhnikov * src/bdf/bdflib.c (_bdf_parse_start): Simplify bpp parsing. 2015-06-23 Werner Lemberg 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. 2015-06-22 Werner Lemberg 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.

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. 2015-06-16 Werner Lemberg Fix Savannah bug #45326. * src/sfnt/sfntpic.h (SFNT_SERVICES_GET): Remove duplicate definitions. 2015-06-07 Werner Lemberg * Version 2.6 released. ======================= Tag sources with `VER-2-6'. * docs/VERSION.DLL: Update documentation and bump version number to 2.6. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, 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/2.5.5/2.6/, s/255/26/. * include/freetype/freetype.h (FREETYPE_MINOR): Set to 6.

Don't include a zero patch level in version string. * builds/freetype.mk: Remove code for computing the version string. 2015-06-06 Ashish Azad Fix Savannah bug #45260. * src/pfr/pfrdrivr.c (pfr_get_kerning): Fix typo. 2015-06-03 Werner Lemberg [truetype] Fix memory leak. Problem reported by Grissiom ; 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. 2015-06-02 Werner Lemberg [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. 2015-06-01 Werner Lemberg [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. 2015-05-31 Werner Lemberg [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. 2015-05-31 Werner Lemberg [truetype] In GX, make intermediate tuplets work at extrema. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition. 2015-05-31 Werner Lemberg [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. 2015-05-28 Werner Lemberg * src/tools/apinames.c (names_dump): Fix invalid reference. Problem reported by Guzman Mosqueda, Jose R . 2015-05-24 Werner Lemberg [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 . 2015-05-23 Werner Lemberg [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). 2015-05-23 Werner Lemberg [truetype] Minor. * src/truetype/ttinterp.h (TT_ExecContext): s/subpixel/subpixel_hinting. * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated. 2015-05-22 Werner Lemberg [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. 2015-05-20 Werner Lemberg [truetype] Minor. * src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod' argument. 2015-05-17 Werner Lemberg [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). 2015-05-12 Chris Liddell [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). 2015-05-12 Chris Liddell [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). 2015-04-29 Alexei Podtelezhnikov [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. 2015-04-28 Werner Lemberg [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. 2015-04-27 Alexei Podtelezhnikov [truetype] Speed up IUP. * src/truetype/ttinterp.c (_iup_worker_interpolate): Separate trivial snapping to the same position from true interpolation. 2015-04-21 Werner Lemberg [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'. 2015-04-21 Werner Lemberg * docs/CHANGES: Updated. 2015-04-21 Werner Lemberg [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. 2015-04-16 Werner Lemberg [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'. 2015-04-10 Werner Lemberg [cff] Update advance width handling to OpenType 1.7. Problem reported by Behdad. * src/cff/cffdrivr.c (cff_get_advances): Handle SFNT case separately. * src/cff/cffgload.c (cff_slot_load): Use advance width and side bearing values from `hmtx' table if present. 2015-04-03 Alexei Podtelezhnikov * src/autofit/afhints.c (af_glyph_hints_reload): Use do-while loop. 2015-04-02 Alexei Podtelezhnikov * src/autofit/aflatin.c (af_latin_hint_edges): Reduce logic. 2015-04-01 Alexei Podtelezhnikov [autofit] Finish the thought. * src/autofit/afhints.c (af_direction_compute): make sure the long arm is never negative so that its `FT_ABS' is not necessary. 2015-04-01 Werner Lemberg [autofit] Call dumper functions for tracing. * src/autofit/afcjk.c (af_cjk_hints_apply): Remove dead code. * src/autofit/afhints.c (af_glyph_hints_dump_points): Minor improvement. * src/autofit/afmodule.c (af_autofitter_load_glyph): Implement it. 2015-04-01 Werner Lemberg [autofit] Make debugging stuff work again. The interface to ftgrid was broken in the series of commits starting with [autofit] Allocate AF_Loader on the stack instead of AF_Module. from 2015-01-14. * src/autofit/afmodule.c (_af_debug_hints_rec) [FT_DEBUG_AUTOFIT]: Use a global AF_GlyphHintsRec object for debugging. (af_autofitter_done, af_autofitter_load_glyph): Updated. * src/autofit/afloader.c (af_loader_init, af_loader_done): Updated. 2015-04-01 Werner Lemberg * src/autofit/afhints.c (af_glyph_hints_done): Fix minor thinko. 2015-03-29 Werner Lemberg [cff] Fix Savannah bug #44629. * src/cff/cf2font.h (CF2_MAX_SUBR), src/cff/cffgload.h (CFF_MAX_SUBRS_CALLS): Set to 16. 2015-03-29 Werner Lemberg [type1, truetype] Make the MM API more flexible w.r.t. `num_coords'. This commit allows `num_coords' to be larger or smaller than the number of available axes while selecting a design instance, either ignoring excess data or using defaults if data is missing. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design): Implement it. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_Design, T1_Set_Var_Design): Ditto. 2015-03-29 Werner Lemberg [type1] Minor. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_Design): Use FT_THROW.

While this doesn't show up with FreeType, exactly the same code leaks with ttfautohint's modified auto-hinter code (which gets used in a slightly different way). It certainly doesn't harm since it is similar to already existing checks in the code for embedded arrays. * src/autofit/afhints.c (af_glyph_hints_reload): Set `max_contours' and `max_points' for all cases. 2015-01-31 Werner Lemberg [autofit] Add support for Thai script.

This fixes a breakage caused by the commit `[raster] Remove 5-level gray AA mode from monochrome rasterizer.'. Problem reported by Markus Trippelsdorf . * src/raster/ftraster.c (ft_black_render): Handle `FT_RASTER_FLAG_AA'. * src/raster/ftrend1.c (ft_raster1_render): Remove gray AA mode remnants. 2015-01-18 Werner Lemberg * src/base/ftobjs.c (FT_New_Library): Fix compiler warning. 2015-01-18 Chris Liddell [raster] Fix Savannah bug #44022. Add fallback for glyphs with degenerate bounding boxes. If a glyph has only one very narrow feature, the bbox can end up with either the width or height of the bbox being 0, in which case no raster memory is allocated and no attempt is made to render the glyph. This is less than ideal when the drop-out compensation in the rendering code would actually result in the glyph being rendered. This problem can be observed with the `I' glyph (gid 47) in the Autodesk RomanS TrueType font. * src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either dimension is zero to explicitly round up/down (instead of simply round). 2015-01-17 Werner Lemberg Add some tools to handle yearly copyright notice updates. We are now following the GNU guidelines: A new release automatically means that the copyright year of all affected files gets updated; it is no longer used to track years of modification changes. * src/tools/update-copyright-year: New Perl script. * src/tools/update-copyright: New shell script that calls `update-copyright-year' on all files. * src/tools/no-copyright: Exceptions that should not be handled by `update-copyright' 2015-01-14 Werner Lemberg * docs/CHANGES: Updated, using a description from Behdad. 2015-01-14 Behdad Esfahbod * src/autofit/afmodule.c (af_autofitter_done): Fix compiler warning. 2015-01-14 Behdad Esfahbod [autofit] Add embedded array of segments and edges. Avoids multiple mallocs per typical glyphs.

(AF_AxisHintsRec): Add two arrays for segments and edges. * src/autofit/afhints.c (af_axis_hints_new_segment): Only allocate data if number of segments exceeds given threshold value. (af_axis_hints_new_edge): Only allocate data if number of edges exceeds given threshold value. (af_glyph_hints_done): Updated. 2015-01-14 Behdad Esfahbod [autofit] Add embedded arrays for points and contours. This avoids at least two malloc calls for typical glyphs. * src/autofit/afhints.h (AF_POINTS_EMBEDDED, AF_CONTOURS_EMBEDDED): New macros. (AF_GlyphHintsRec): Add two arrays for contours and points. * src/autofit/afhints.c (af_glyph_hints_init, af_glyph_hints_done): Updated. (af_glyph_hints_reload): Only allocate data if number of contours or points exceeds given threshold values. 2015-01-14 Behdad Esfahbod [autofit] Allocate hints object on the stack. This avoids one malloc per load. * src/autofit/afloader.h (AF_LoaderRec): Change type of `hints' to `AF_GlyphHints'. Update prototype. * src/autofit/afloader.c (af_loader_init): Use `AF_GlyphHints' parameter instead of `FT_Memory'. (af_loader_done): Directly reset `load_hints'. (af_loader_load_g): Updated. * src/autofit/afmodule.c (af_autofitter_load_glyph): Use local `hints' object. 2015-01-14 Behdad Esfahbod [autofit] Reuse slot glyph loader. No need to create a new glyph loader; we can reuse the one from `slot->internal->loader'. It's hard to tell why it was written that way originally, but new code looks sound and correct to me, and avoids lots of allocations. * src/autofit/afloader.c (af_loader_init): Change return type to `void'. Don't call `FT_GlyphLoader_New'. (af_loader_reset): Don't call `FT_GlyphLoader_Rewind'. (af_loader_load_g): Update code to use `internal->loader', which doesn't need copying of data. * src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member. Update prototype. * src/autofit/afmodule.c (af_autofitter_load_glyph): Updated. 2015-01-14 Behdad Esfahbod [autofit] Remove (unused) support for composite glyphs. We never have to deal with composite glyphs in the autohinter, as those will be loaded into FORMAT_OUTLINE by the recursed `FT_Load_Glyph' function. In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies FT_LOAD_NO_HINTING: /* resolve load flags dependencies */ if ( load_flags & FT_LOAD_NO_RECURSE ) load_flags |= FT_LOAD_NO_SCALE | FT_LOAD_IGNORE_TRANSFORM; if ( load_flags & FT_LOAD_NO_SCALE ) { load_flags |= FT_LOAD_NO_HINTING | FT_LOAD_NO_BITMAP; load_flags &= ~FT_LOAD_RENDER; } and as such the auto-hinter is never called. Thus, the recursion in `af_loader_load_g' never actually happens. So remove the depth counter as well. * src/autofit/afloader.c (af_loader_load_g): Remove `depth' parameter. : Remove associated code. (af_loader_load_glyph): Updated. 2015-01-14 Behdad Esfahbod [raster] Fix uninitialized memory access. Apparently `ras.cProfile' might be uninitialized. This will be the case if `ras.top == ras.cProfile->offset', as can be seen in `End_Profile'. The overshoot code introduced in a change `Fix B/W rasterization of subglyphs with different drop-out modes.' (from 2009-06-18) violated this, accessing `ras.cProfile->flags' unconditionally just before calling `End_Profile' (which then detected that `cProfile' is uninitialized and didn't touch it). This was harmless, and was not detected by valgrind before because the objects were allocated on the `raster_pool', which was always initialized. With recent change to allocate raster buffers on the stack, valgrind now reported this invalid access. * src/raster/ftraster.c (Convert_Glyph): Don't access an uninitialized `cProfile'. 2015-01-14 Behdad Esfahbod [smooth] Fix uninitialized memory access. Looks like `ras.span_y' could always be used without initialization. This was never detected by valgrind before because the library-wide `raster_pool' was used for the worker object and `raster_pool' was originally zero'ed. But subsequent reuses of it were using `span_y' uninitialized. With the recent change to not use `render_pool' and allocate worker and buffer on the stack, valgrind now detects this uninitialized access. * src/smooth/ftgrays.c (gray_raster_render): Initialize `ras.span_y'. 2015-01-14 Behdad Esfahbod [base] Don't initialize unused `driver->glyph_loader'. * src/base/ftobjs.c (Destroy_Driver): Don't call `FT_GlyphLoader_Done'. (FT_Add_Module): Don't call `FT_GlyphLoader_New'. 2015-01-14 Behdad Esfahbod [base] Don't allocate `library->raster_pool' anymore. It's unused after the following commits: [raster] Allocate render pool for mono rasterizer on the stack. [raster] Remove 5-level gray AA mode from monochrome rasterizer. The value of FT_RENDER_POOL_SIZE still serves the purpose it used to serve, which is, to adjust the pool size. But the pool is now allocated on the stack on demand. * src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement. 2015-01-14 Behdad Esfahbod [base] Do not reorder library->renderers upon use. Instead of keeping `library->renderers' in a MRU order, just leave it as-is. The MRU machinery wasn't thread-safe. With this patch, rasterizing glyphs from different faces from different threads doesn't fail choosing rasterizer (FT_Err_Cannot_Render_Glyph). Easiest to see that crash was to add a `printf' (or otherwise let thread yield in FT_Throw with debugging enabled). * src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c (FT_Outline_Render): Don't call `FT_Set_Renderer'. 2015-01-14 Behdad Esfahbod [raster] Allocate render pool for mono rasterizer on the stack. Instead of using the `render_pool' member of `FT_Library' that is provided down to the rasterizer, completely ignore that and allocate needed objects on the stack instead. With this patch, rasterizing glyphs from different faces from different threads doesn't crash in the monochrome rasterizer. * src/raster/ftraster.c (black_TRaster): Remove `buffer', `buffer_size', and `worker' members. (ft_black_render): Create `buffer' locally. (ft_black_reset): Updated. 2015-01-14 Behdad Esfahbod [raster] Remove 5-level gray AA mode from monochrome rasterizer. It was off by default and couldn't be turned on at runtime. And the smooth rasterizer superceded it over ten years ago. No point in keeping. Comments suggested that it was there for compatibility with FreeType 1. 550 lines down. * src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING, RASTER_GRAY_LINES): Remove macros and all associated code. (black_TWorker): Remove `gray_min_x' and `gray_max_x'. (black_TRaster): Remove `grays' and `gray_width'. (Vertical_Sweep_Init, Vertical_Sweep_Span, Vertical_Sweep_Drop, ft_black_render): Updated. * src/raster/ftrend1.c (ft_raster1_render): Simplify code. (ft_raster5_renderer_class): Removed. 2015-01-14 Behdad Esfahbod [smooth] Allocate render pool for smooth rasterizer on the stack. Instead of using the `render_pool' member of `FT_Library' that is provided down to the rasterizer, completely ignore that and allocate needed objects on the stack instead. With this patch, rasterizing glyphs from different faces from different threads doesn't crash in the smooth rasterizer.

(gray_raster_render): Create `buffer', `buffer_size', and `band_size' locally. (gray_raster_reset): Updated. 2015-01-14 Behdad Esfahbod [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver. Previously the code had stipulation for using a per-TT_Size exec context if `size->debug' was true. But there was no way that `size->debug' could *ever* be true. As such, the code was always using the singleton `TT_ExecContext' that was stored in `TT_Driver'. This was, clearly, not threadsafe. With this patch, loading glyphs from different faces from different threads doesn't crash in the bytecode loader code. * src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member. (TT_DriverRec): Remove `context' member. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove `TT_ExecContext' code related to a global `TT_Driver' object. (tt_driver_done): Don't remove `TT_ExecContext' object here but ... (tt_size_done_bytecode): ... here. (tt_driver_init): Don't create `TT_ExecContext' object here but ... (tt_size_init_bytecode): ... here, only on demand. * src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug code. (TT_New_Context): Remove `TT_ExecContext' code related to a global `TT_Driver' object. * src/truetype/ttinterp.h: Updated. * src/truetype/ttgload.c (TT_Hint_Glyph, tt_loader_init): Updated. 2015-01-14 Behdad Esfahbod [autofit] Allocate AF_Loader on the stack instead of AF_Module. Stop sharing a global `AF_Loader'. Allocate one on the stack during glyph load. Right now this results in about 25% slowdown, to be fixed in a following commit. With this patch loading glyphs from different faces from different threads doesn't immediately crash in the autohinting loader code. Bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1164941 * src/autofit/afloader.c (af_loader_init): Pass `AF_Loader' and `FT_Memory' instead of `AF_Module' as arguments. (af_loader_reset, af_loader_load_glyph): Also pass `loader' as argument. (af_loader_done): Use `AF_Loader' instead of `AF_Module' as argument. * src/autofit/afmodule.c (af_autofitter_init): Don't call `af_loader_init'. (af_autofitter_done): Don't call `af_loader_done'. (af_autofitter_load_glyph): Use a local `AF_Loader' object. * src/autofit/afloader.h: Include `afmodule.h'. Update prototypes. Move typedef for `AF_Module' to... * src/autofit/afmodule.h: ... this place. No longer include `afloader.h'. 2015-01-14 Behdad Esfahbod * src/type42/t42objs.h (T42_DriverRec): Remove unused member. 2015-01-12 Werner Lemberg Fix Savannah bug #43976. Assure that FreeType's internal include directories are found before `CPPFLAGS' (which might be set by the user in the environment), and `CPPFLAGS' before `CFLAGS'. * builds/freetype.mk (FT_CFLAGS): Don't add `INCLUDE_FLAGS'. (FT_COMPILE): Make this a special variable for compiling only the files handled in `freetype.mk'. (.c.$O): Removed, unused. * src/*/rules.mk (*_COMPILE): Fix order of include directories. 2015-01-11 Werner Lemberg [truetype] Prettyfing. * src/truetype/ttinterp.c (project, dualproj, fast_project, fast_dualproj): Rename to... (PROJECT, DUALPROJ, FAST_PROJECT, FAST_DUALPROJ): ... this. 2015-01-11 Werner Lemberg * src/truetype/ttinterp.c (Ins_JROT, Ins_JROF): Simplify. Based on a patch from Behdad. 2015-01-11 Werner Lemberg * src/truetype/ttinterp.c (Ins_SxVTL): Simplify function call. 2015-01-11 Werner Lemberg * src/truetype/ttinterp.c (Normalize): Remove unused argument. 2015-01-11 Werner Lemberg [truetype] More macro expansions. * src/truetype/ttinterp.c (FT_UNUSED_EXEC): Remove macro by expansion. 2015-01-11 Werner Lemberg [truetype] More macro expansions. * src/truetype/ttinterp.c (INS_ARG): Remove macro by expansion, adjusting funtion calls where necessary.

(Ins_SxyTCA): New function. 2015-01-10 Werner Lemberg [truetype] Remove TT_CONFIG_OPTION_INTERPRETER_SWITCH. Behdad suggested this code simplification, and nobody objected... * include/config/ftoption.h, devel/ftoption.h (TT_CONFIG_OPTION_INTERPRETER_SWITCH): Remove. * src/truetype/ttinterp.c [TT_CONFIG_OPTION_INTERPRETER_SWITCH]: Remove related code. (ARRAY_BOUND_ERROR): Use do-while loop. 2015-01-10 Werner Lemberg [truetype] More macro expansions. * src/truetype/ttinterp.c, src/truetype/ttinterp.h (EXEC_ARG_, EXEC_ARG): Remove by replacing with expansion. 2015-01-10 Werner Lemberg [truetype] More macro expansions. Based on a patch from Behdad. * src/truetype/ttinterp.c (SKIP_Code, GET_ShortIns, NORMalize, SET_SuperRound, ROUND_None, INS_Goto_CodeRange, CUR_Func_move, CUR_Func_move_orig, CUR_Func_round, CUR_Func_cur_ppem, CUR_Func_read_cvt, CUR_Func_write_cvt, CUR_Func_move_cvt, CURRENT_Ratio, INS_SxVTL, COMPUTE_Funcs, COMPUTE_Round, COMPUTE_Point_Displacement, MOVE_Zp2_Point): Remove by replacing with expansion.
