| [cff] Make Adobe CFF engine work correctly on 64bit hosts. | |
| Reported by numerous people on the `freetype-devel' list. Without | |
| this fix, glyphs aren't properly aligned on a common baseline. | |
| On 64bit systems, `FT_Pos' expands to `long int', having a width of | |
| 64bit. `CF2_Fixed' expands to `int' which is normally 32bit wide on | |
| 64bit hosts also. Wrong casts filled up the blues arrays with | |
| incorrect values. Note that all blues values are accessed with the | |
| `cf2_blueToFixed' macro which handles the 64bit to 32bit conversion. | |
| * src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues, | |
| cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for | |
| `data', not `CF2_Fixed'. | |

| cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated. | |
| * src/cff/cf2blues.c (cf2_blues_init): Updated. | |

| More fixes for clang's `sanitize' feature. | |
| * src/base/ftcalc.c (FT_DivFix): Use unsigned values for | |

| computations and convert to signed as the last step. | |
| * src/cff/cf2fixed.h (cf2_intToFixed, cf2_fixedToInt, | |
| cf2_fracToFixed): Avoid shifts of negative values. | |
| (cf2_intToFrac, cf2_fixedToFrac, cf2_fixedTo26Dot6): Removed, | |
| unused. | |
| * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR, | |
| default>: Use unsigned values for computations and convert to signed | |
| as the last step. | |
| Use proper types in tracing messages. | |
| * src/cff/cffgload.c (cff_decoder_parse_charstrings): Use unsigned | |
| values for computation of operands and convert to signed as the last | |
| step. | |
| Use proper type in tracing message. | |

| 2013-04-13 Werner Lemberg <wl@gnu.org> | |
| [cff] Add a new Type 2 interpreter and hinter. | |
| This work, written by Dave Arnold <darnold@adobe.com> and fully | |
| integrated into FreeType by me, is a donation by Adobe in | |
| collaboration with Google. It is vastly superior to the old CFF | |
| engine, and it will replace it soon. Right now, it is still off by | |
| default, and you have to explicitly select it using the new | |
| `hinting-engine' property of the cff driver. | |
| For convenience, (most of) the new files are committed separately. | |
| * include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro. | |
| * include/freetype/ftcffdrv.h: New file to access CFF driver | |
| properties. | |
| * include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error | |
| code. | |
| * include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints', | |
| and `cf2interp'. | |
| * src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'. | |
| * src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine' | |
| and `no_stem_darkening'. | |
| * src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'. | |
| * src/cff/cff.c: Include new files. | |
| * src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle | |
| `hinting-engine' and `no-stem-darkening' properties (only the Adobe | |
| engine listens to them). | |
| * src/cff/cffgload.c: Include `cf2ft.h'. | |
| (cff_decoder_prepare): Initialize `current_subfont'. | |
| (cff_build_add_point): Handle Adobe engine which uses 16.16 | |
| coordinates. | |
| (cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING | |
| separately. | |
| Choose rendering engine based on `hinting_engine' property. | |
| * src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe | |
| engine. | |
| * src/cff/cffobjs.c: Include FT_CFF_DRIVER_H. | |
| (cff_driver_init): Set default property values. | |
| * src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files. | |
| * src/cff/cf2*.*: New files, containing the Adobe engine. | |
| 2013-04-12 Werner Lemberg <wl@gnu.org> | |
| [cff] Minor code administration issues. | |
| * src/cff/cffgload.c (check_points): Rename to... | |
| (cff_check_points): ...this and make it FT_LOCAL. | |
| (cff_builder_add_point, cff_builder_add_point1, | |
| cff_builder_start_point, cff_builder_close_contour, | |
| cff_lookup_glyph_by_stdcharcode, cff_get_glyph_data, | |
| cff_free_glyph_data): Make them FT_LOCAL. | |
| * src/cff/cffgload.h: Updated. | |
| 2013-04-12 Werner Lemberg <wl@gnu.org> | |
| Add output bitmap checksums. | |
| Use `FT2_DEBUG=bitmap:3' for tracing. | |

| http://openwall.info/wiki/people/solar/software/public-domain-source-code/md5 | |
| * include/freetype/internal/fttrace.h: Add `bitmap'. | |
| * src/base/ftobjs.c [FT_DEBUG_LEVEL_TRACE]: Include `md5.c' | |
| (FT_Render_Glyph_Internal) [FT_DEBUG_LEVEL_TRACE]: For tracing, | |
| convert resulting bitmap to a uniform format and compute a checksum. | |
| Use `bitmap' category for the tracing message. | |
| * src/base/rules.mk (BASE_H): Updated. | |
| * docs/LICENSE.TXT: Updated. | |
| 2013-04-12 Werner Lemberg <wl@gnu.org> | |

| 2013-04-03 Werner Lemberg <wl@gnu.org> | |
| [bdf] Fix Savannah bug #38589. | |
| * src/bdf/bdflib.c (_bdf_readstream): Thinko. | |
| 2013-03-31 Werner Lemberg <wl@gnu.org> | |
| * configure: Use egrep, not grep. | |
| Problem reported Mojca Miklavec <mojca.miklavec.lists@gmail.com>. | |
| 2013-03-29 Werner Lemberg <wl@gnu.org> | |
| * include/freetype/ftlcdfil.h: Add description of color filtering. | |
| Based on a contribution from Antti S. Lankila <alankila@bel.fi> | |
| (Savannah bug #38607). | |
| 2013-03-23 Werner Lemberg <wl@gnu.org> | |
| [autofit] Minor. | |
| * src/autofit/afmodule.c (af_property_set): Typo. | |
| (af_autofitter_init, af_autofitter_done): Use cast. | |
| 2013-03-21 Werner Lemberg <wl@gnu.org> | |
| * configure: Automatically test for `gmake' also. | |
| Suggested by Mojca Miklavec <mojca.miklavec.lists@gmail.com>. | |
| 2013-03-21 Peter Breitenlohner <peb@mppmu.mpg.de> | |
| Respect CONFIG_SHELL from the environment. | |
| Some large packages using FreeType have to use a broken (deficient) | |
| /bin/sh. The configure scripts (as generated by Autoconf) are | |
| clever enough to find a better shell and put that one into the | |
| environment variable CONFIG_SHELL. If that environment variable is | |
| already set the script skips the test and assumes to be already | |
| running under a good shell. | |
| * builds/unix/detect.mk: Honour CONFIG_SHELL. | |
| * builds/unix/unix-def.in (SHELL): Define. | |
| 2013-03-21 Werner Lemberg <wl@gnu.org> | |
| Fix Savannah patch #7971. | |
| * configure: Handle MAKE environment variable also. | |
| 2013-03-17 Werner Lemberg <wl@gnu.org> | |
| Fix Savannah bug #38538. | |
| * builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c, | |
| builds/wince/ftdebug.c (FT_Throw): Add function. | |
| 2013-03-17 Werner Lemberg <wl@gnu.org> | |
| [raster] Remove dead code. | |
| * src/raster/rastpic.c (ft_raster1_renderer_class_pic_init) | |
| src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it. | |
| 2013-03-17 Werner Lemberg <wl@gnu.org> | |
| * src/pshinter/pshpic.h (GET_PIC): Use correct container. | |
| 2013-03-15 Werner Lemberg <wl@gnu.org> | |
| * include/freetype/ftmoderr.h: Fix commit from 2013-03-11. | |
| The previous version was not backwards compatible. Reported by | |
| Behdad. | |
| 2013-03-14 Werner Lemberg <wl@gnu.org> | |
| */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate. | |
| FT_Err_XXX and friends are no longer directly used in the source | |
| code. | |
| 2013-03-14 Werner Lemberg <wl@gnu.org> | |
| New error management macros. | |
| * include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to... | |
| * include/freetype/fttypes.h: ... this file. | |
| (FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New | |
| macros. | |
| * include/freetype/freetype.h: Updated. | |
| 2013-03-14 Werner Lemberg <wl@gnu.org> | |
| */*: Use FT_Err_Ok only. | |
| This is a purely mechanical conversion. | |
| 2013-03-14 Werner Lemberg <wl@gnu.org> | |
| */*: Use `FT_THROW'. | |
| This is essentially a mechanical conversion, adding inclusion of | |
| `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for | |
| stand-alone compiling modes of the rasterizer modules. | |
| To convert the remaining occurrences of FT_Err_XXX and friends it is | |
| necessary to rewrite the code. Note, however, that it doesn't harm | |
| if some cases are not handled since FT_THROW is a no-op. | |
| 2013-03-13 Werner Lemberg <wl@gnu.org> | |
| Introduce `FT_THROW' macro. | |
| The idea is to replace code like | |
| return FT_Err_Foo_Bar; | |
| or | |
| return CFF_Err_Foo_Bar; | |
| with | |
| return FT_THROW( Foo_Bar ); | |
| The FT_THROW macro has two functions: | |
| . It hides the module specific prefix. | |
| . In debug mode, it calls the empty function `FT_Throw' which can | |
| be thus used to set a breakpoint. | |
| * include/freetype/internal/ftdebug.h (FT_THROW): New macro. | |
| (FT_Throw): New prototype. | |
| * src/base/ftdebug.c (FT_Throw): New function. | |
| 2013-03-12 Werner Lemberg <wl@gnu.org> | |
| Remove `FT_KEEP_ERR_PREFIX'. | |
| The idea is to always have FT_ERR_PREFIX available internally. | |
| * include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard | |
| undefinition of FT_ERR_PREFIX | |
| * src/gxvalid/gxverror.h, src/otvalid/otverror.h, | |
| src/sfnt/sferrors.h: Updated. | |
| 2013-03-11 Werner Lemberg <wl@gnu.org> | |
| [gxvalid] Fix module error. | |
| * src/gxvalid/gxverror.h (FT_ERR_BASE): Define as | |
| FT_Mod_Err_GXvalid. | |
| * include/freetype/ftmoderr.h: Add module error for `GXvalid'. | |
| 2013-03-11 Werner Lemberg <wl@gnu.org> | |
| Always use module related error codes. | |
| * src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c | |
| (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use | |
| `FT_ERROR_BASE'. | |
| * src/type1/t1load.c (parse_encoding): Use | |
| T1_Err_Unknown_File_Format. | |
| 2013-03-08 Werner Lemberg <wl@gnu.org> | |
| [cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also. | |
| Problem reported by Khaled Hosny <khaledhosny@eglug.org>. | |
| * src/cff/cffgload.c (cff_slot_load): Implement it. | |
| 2013-02-23 Alexei Podtelezhnikov <apodtele@gmail.com> | |
| [base] Fix commit ab02d9e8. | |
| * src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22. | |
| 2013-02-19 Alexei Podtelezhnikov <apodtele@gmail.com> | |
| [base] New bisecting BBox_Cubic_Check (disabled). | |
| * src/base/ftbbox.c (BBox_Cubic_Check): New bisecting algorithm | |
| for extremum search built around simple condition that defines | |
| which half contains the extremum. | |
| 2013-02-18 Alexei Podtelezhnikov <apodtele@gmail.com> | |
| [tools] Update BBox testing tool. | |
| * src/tools/test_bbox.c: Add another cubic outline with exact BBox. | |
| (REPEAT): Increase the number of benchmarking cycles. | |
| (profile_outline): Tweak output formatting. | |
| 2013-02-02 Werner Lemberg <wl@gnu.org> | |
| Fix Savannah bug #38235. | |
| * builds/unix/configure.raw: Don't generate `freetype-config' and | |
| `freetype.pc'. | |
| * builds/unix/unix-def.in (FT2_EXTRA_LIBS, LIBBZ2, LIBZ, | |
| build_libtool_libs, ft_version): New variables to be substituted. | |
| (freetype-config, freetype.pc): New rules to generate those files. | |
| * builds/unix/freetype-config.in: Remove code for handling `rpath'. | |
| The use of $rpath has been accidentally removed in a patch from | |
| 2009-12-22, and apparently noone has missed it since. | |
| Use `%' instead of `@' as a variable substitution marker. | |
| Use quotes. | |
| * builds/unix/freetype.in: Use `%' instead of `@' as a variable | |
| substitution marker. | |
| Use quotes. | |
| 2013-02-07 Werner Lemberg <wl@gnu.org> | |
| * src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables. | |
| BTW, Greg agrees that the OpenType specification is missing the list | |
| of GS variables which will always be reset to the default values | |
| after the `prep' table has been executed. | |
| 2013-02-06 Werner Lemberg <wl@gnu.org> | |
| * src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points. | |
| Up to now, we simply took a snapshot of the Graphics State after the | |
| `prep' table has been executed, and right before a glyph's bytecode | |
| was run it got reloaded. However, as Greg Hitchcock has told us in | |
| private communication, reference points get reset to zero in the MS | |
| rasterizer and we follow in due course. While reasonable, this is | |
| undocumented behaviour. | |
| Most notably, this fixes the rendering of Arial's `x' glyph in | |
| subpixel hinting mode. | |
| 2013-02-05 Werner Lemberg <wl@gnu.org> | |
| [truetype] A better fix for Savannah bug #38211. | |
| * src/truetype/ttinterp.c (Ins_IP): Implement identical behaviour to | |
| MS rasterizer if rp1 == rp2 (confirmed by Greg Hitchcock). | |
| 2013-02-01 Alexei Podtelezhnikov <apodtele@gmail.com> | |
| [pcf] Streamline parsing of PCF encoding table. | |
| * src/pcf/pcfread.c (pcf_get_encodings): Use simpler double for-loop. | |
| Reallocate array instead of using temporary storage. | |
| 2013-02-01 Werner Lemberg <wl@gnu.org> | |
| Fix Savannah bug #38227. | |
| * builds/unix/freetype-config.in: Set LC_ALL. | |
| 2013-02-01 Werner Lemberg <wl@gnu.org> | |
| Fix Savannah bug #38221. | |
| This complements commit 83c0ebab. | |
| * src/base/ftcalc.c (FT_MulDiv_No_Round): Don't enclose with | |
| `TT_USE_BYTECODE_INTERPRETER'. | |
| 2013-02-01 Werner Lemberg <wl@gnu.org> | |
| [truetype] Fix Savannah bug #38211. | |
| * src/truetype/ttinterp.c (Ins_IP): Make FreeType behave identical | |
| to other interpreters if rp1 == rp2 (which is invalid). | |
| 2013-01-28 Alexei Podtelezhnikov <apodtele@gmail.com> | |
| [base] Small optimization of BBox calculation. | |
| * src/base/ftbbox.c (BBox_Cubic_Check): Use FT_MSB function in | |
| scaling algorithm. | |
| 2013-01-26 Infinality <infinality@infinality.net> | |
| [truetype] Minor formatting fix. | |

| 2013-01-26 Infinality <infinality@infinality.net> | |
| [truetype] Align more to ClearType whitepaper for sph. | |
| * include/freetype/internal/tttypes.h (TT_FaceRec): Add flags | |
| for detected opcode patterns and compatibility mode. | |
| * src/truetype/ttgload.c (tt_loader_init): Complete conditional. | |
| * src/truetype/ttinterp.c: Updated. | |
| Remove SPH_DEBUG and replace with FT_TRACE7. | |
| (DO_RS): More conditions. | |
| (Ins_FDEF): Add more opcode detection patterns. | |
| More specific conditions when flagging an fdef. | |
| Make compatibility mode only turn on when delta fdefs are found. | |
| (Ins_CALL, Ins_LOOPCALL): Set flags for currently executed fdef. | |
| (Ins_SHPIX): Remove logic to handle ttfautohinted fonts. | |
| Simplify conditionals where possible. | |
| Use `&' instead of `%' operator for dumb compilers. | |
| (Ins_MIAP): Adjust twilight zone conditional. | |
| Ensure `ignore_x_mode' is on when testing sph conditionals. | |
| (Ins_MIRP): Ensure `ignore_x_mode' is on when testing sph | |

| [sfnt] Fix broken pointer overflow checks. | |
| Many compilers such as gcc and clang optimize away pointer overflow | |
| checks `p + n < p', because pointer overflow is undefined behavior. | |
| Use a safe form `n > p_limit - p' instead. | |
| Also avoid possible integer overflow issues, for example, using | |
| `num_glyphs > ( p_limit - p ) / 2' rather than `num_glyphs * 2' | |
| given a large `num_glyphs'. | |

| [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. | |

| [truetype] Improve accuracy of normalization of short vectors. | |
| Unit vector components are stored as 2.14 fixed-point numbers. In | |
| order to calculate all 14 bits accurately, a short vector to be | |
| normalized has to be upscaled to at least 14 bits before its length | |
| is calculated. This has been safe since accurate CORDIC algorithms | |
| were adopted. | |
| * src/truetype/ttinterp.c (Normalize): Scale short vectors by 0x4000. | |
| 2013-01-12 Alexei Podtelezhnikov <apodtele@gmail.com> | |
| [truetype] Kill very old vector normalization hacks. | |
| Back in the days, vector length calculations were not very accurate | |
| and the vector normalization function, Normalize, had to meticulously | |
| correct the errors for long vectors [commit b7ef2b096867]. It was no | |
| longer necessary after accurate CORDIC algorithms were adopted, but | |
| the code remained. It is time to kill it. | |

| [base] Improve trigonometric core. | |
| FreeType used to rely on a 24-step iteration CORDIC algorithm to | |
| calculate trigonometric functions and rotate vectors. It turns out | |
| that once the vector is in the right half-plane, the initial rotation | |
| by 63 degrees is not necessary. The algorithm is perfectly capable | |
| to converge to any angle starting from the second 45 degree rotation. | |
| This patch removes the first rotation and makes it a 23-step CORDIC | |
| algorithm. | |
| * src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macro | |

| [truetype] Scale F_dot_P down. | |
| The dot product between freeVector and projVector or cosine of | |
| the angle between these FT_F2Dot14 unit vectors used to be scaled up | |
| by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P. | |
| This patch scales the value down by 2^14 instead, which simplifies | |
| its use throughout the bytecode interpreter. | |
| This does not lead to the loss of precision because the lower bits | |
| are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8) | |
| for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666. | |
| These vectors are stored as (0x4000,0) and (0x2666,0x3333) after | |
| rounding and F_dot_P is assigned 0x26660000. The lower bits were | |
| already lost while rounding the unit vector components. | |
| Besides code simplification, this change can lead to better | |
| performance when FT_MulDiv with the scaled-down F_dot_P is less | |
| likely to use the costly 64-bit path. We are not changing the type | |
| of F_dot_P to FT_F2Dot14 at this point. | |
| * src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14 | |
| bits and modify its use accordingly. | |
| (Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify | |

| * src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary | |
| assignment of F_dot_P to its theoretical maximum in case we decide | |
| to scale back its type later. | |

| http://www.infinality.net/fedora/linux/zips/freetype-infinality-2.4.10-20120616_01-x86_64.tar.bz2 | |
| which addresses various enhancements of the auto-hinter. Without | |
| properties to control a module's metadata it wasn't possible to | |
| adapt the patches because everything was originally controlled by | |
| environment variables which I consider not suitable in general. | |

| 2012-09-15 Werner Lemberg <wl@gnu.org> | |

| Fix `checking if gcc static flag -static works' test. | |
| On my linux build tree, I receive yes answer in in every package I | |

| `-static' works | |
| On freetype, no is received, unless bzip2 and zlib are disabled using | |
| ./configure --without-bzip2 --without-zlib | |
| The reason is that bzip2 and zlib tests add `-lz' and `-lbz2' to | |

| 2012-06-18 Infinality <infinality@infinality.net> | |
| [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, | |

| `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. | |

| [autofit] Return correct linear advance width values. | |
| This was quite a subtle bug which accidentally showed up with glyph | |
| `afii10023' of arial.ttf (version 2.76). This glyph is a composite; | |
| the first component, `E', has an advance width of 1366 font units, | |
| while the advance width of the composite itself (which looks like | |
| uppercase `E' with dieresis) is 1367 font units. I think this is | |
| actually a bug in the font itself, because there is no reason that | |
| this glyph has not the same width as uppercase `E' without the | |
| dieresis. Anyway, it helped identify this problem. | |
| Using the TrueType hinter, the correct value (1367) of `afii10023' | |
| was returned, but the autohinter mysteriously returned 1366. | |
| Digging in the code showed that the autohinter recursively calls | |
| FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load | |
| flag. However, the `linearHoriAdvance' field is still returned as a | |
| scaled value. To avoid scaling twice, the old code in autofit reset | |
| `linearHoriAdvance', using the `horiAdvance' field. This seemed to | |
| work since FT_LOAD_NO_SCALE was in use, but it failed actually, | |
| because `horiAdvance' is defined as the distance of the first | |
| subglyph's phantom points, which in turn are initialized using the | |
| advance width of the first subglyph. And as the given example | |
| shows, these widths can differ. | |
| * src/autofit/afloader.c (af_loader_load_g): Temporarily set | |
| FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled | |
| values for the linear advance widths. | |

| 2012-03-03 Werner Lemberg <wl@gnu.org> | |
| Fix Savannah bug #35660. | |
| For some divisions, we use casts to 32bit entities. Always guard | |
| against division by zero with these casts also. | |
| * src/base/ftcalc.c (ft_div64by32): Remove redundant cast. | |
| (FT_MulDiv, FT_MulDiv_No_Round): Add 32bit cast. | |
| (FT_DivFix): Add 32bit cast (this omission triggered the bug). | |
| 2012-03-03 Werner Lemberg <wl@gnu.org> | |
| [psaux] Fix handling of track kerning. | |
| * src/psaux/afmparse.c (afm_parse_track_kern): Don't inverse sign | |
| for `min_kern'. It is indeed quite common that track kerning | |
| *increases* spacing for very small sizes. | |

| [psaux] Fix Savannah bug #35657. | |
| If in function `skip_spaces' the routine `skip_comment' comes to the | |
| end of buffer, `cur' is still increased by one, so we need to check | |
| for `p >= limit' and not `p == limit'. | |

| [bdf] Fix Savannah bug #35641. | |
| * src/bdf/bdflib.c (_bdf_parse_glyphs) <DWIDTH, BBX>: Abort if | |

| Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()' | |
| are renamed with `ft_' suffixes. | |
| * src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed | |
| to `ft_raccess_rule_by_darwin_vfs()'. | |
| * src/base/ftobjs.c: Ditto. | |
| * src/base/ftrfork.c: Declarations of FT_RFork_Rule, | |
| raccess_guess_rec, are moved to... | |
| * include/freetype/internal/ftrfork.h: Here. | |
| * include/freetype/internal/ftrfork.h: | |
| FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined | |
| to replace raccess_guess_table[] in both of PIC and non-PIC | |
| modes. | |
| * src/base/ftrfork.c: raccess_guess_table[] array is rewritten | |
| by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}. | |
| * src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table' | |
| storage. (FT_RACCESS_GUESS_TABLE_GET): New macro to retrieve | |
| the function pointer from `ft_raccess_guess_table' storage in | |
| `BasePIC' structure. | |
| * src/base/ftrfork.c (FT_Raccess_Guess): Rewritten with | |
| FT_RACCESS_GUESS_TABLE_GET. | |
| (raccess_get_rule_type_from_rule_index): Add `library' as the | |
| first argument to the function, to retrieve the storage of | |
| `ft_raccess_guess_table' from it. Also `raccess_guess_table' | |
| is replaced by FT_RACCESS_GUESS_TABLE_GET. | |

| [autofit] Fix the inclusion of `aflatin2.h' in PIC file. | |
| * src/autofit/afpic.c: Include `aflatin2.h' when | |
| FT_OPTION_AUTOFIT2 is defined, as afglobal.c does so. | |
| Unconditionally inclusion causes declared but unimplemented | |
| warning by GCC 4.6. | |
| 2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| [cff] Remove redundant declarations of cff_cmap_XXX_class_rec. | |
| * src/cff/cffpic.c: The declarations of | |
| FT_Init_Class_cff_cmap_encoding_class_rec() and | |
| FT_Init_Class_cff_cmap_unicode_class_rec() are removed. | |
| They can be obtained by the inclusion of cffcmap.h. | |
| cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares | |
| FT_Init_Class_cff_cmap_encoding_class_rec() etc in PIC mode. | |
| 2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| Fix redundant declaration warning in PIC mode. | |
| Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were | |
| designed to declare xxx_pic_{free,init} by themselves. | |
| Because these macros are used at the end of the module | |
| interface (e.g. ttdriver.c) and the wrapper source to build | |
| a module as a single object (e.g. truetype.c) includes | |
| the PIC file (e.g. ttpic.c) before the module interface, | |
| these macros are expanded AFTER xxx_pic_{free,init} body | |
| when the modules are built as single object. | |
| The declaration after the implementation causes the redundant | |
| declaration warnings, so the declarations are moved to module | |
| PIC headers (e.g. ttpic.h). Separating to other header files | |
| are needed for multi build. | |
| * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER): | |
| Remove class_##_pic_free and class_##_pic_init declarations. | |
| * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER, | |
| FT_DEFINE_MODULE): Ditto. | |
| * src/base/basepic.h: Insert a comment and fix coding style. | |
| * src/autofit/afpic.h: Declare autofit_module_class_pic_{free, | |
| init}. | |
| * src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}. | |
| * src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free, | |
| init}. | |
| * src/psnames/pspic.h: Declare psnames_module_class_pic_{free, | |
| init}. | |
| * src/raster/rastpic.h: Declare | |
| ft_raster{1,5}_renderer_class_pic_{free,init} | |
| * src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}. | |
| * src/smooth/ftspic.h: Declare | |
| ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}. | |
| * src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}. | |
| 2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |

| * src/psnames/pspic.c: Include `psnamerr.h'. | |
| 2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| [base] Fix a dereference of uninitialized variable in PIC mode. | |
| * src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be | |
| set before derefering to obtain `library'. The initialization | |
| of `clazz', `glyph', `library' and NULL pointer check are | |
| reordered to minimize PIC conditonals. | |
| 2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| [base] Insert explicit cast for GCC 4.6 in PIC mode. | |
| * src/base/ftinit.c (FT_Add_Default_Modules): Under PIC | |
| configuration, FT_DEFAULT_MODULES_GET returns | |
| FT_Module_Class** pointer, GCC 4.6 warns that | |
| const FT_Module_Class* const* variable is warned as | |
| inappropriate to store it. To calm it, explicit cast is | |
| inserted. Also `library' is checked to prevent the NULL | |
| pointer dereference in FT_DEFAULT_MODULES_GET. | |
| 2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| Fix PIC build broken by d9145241fe378104ba4c12a42534549faacc92e6. | |
| Under PIC configuration, FT_{CFF,PSCMAPS,SFNT,TT}_SERVICES_GET | |
| take no arguments but derefer the variable named `library' | |
| internally. | |
| * src/cff/cffdrivr.c (cff_get_interface): Declare `library' and | |
| set it if non-NULL driver is passed. | |
| * src/truetype/ttdriver.c (tt_get_interface): Ditto. | |
| * src/sfnt/sfdriver.c (sfnt_get_interface): Declare `library' | |
| under PIC configuration, and set it if non-NULL module is given. | |
| * src/psnames/psmodule.c (psnames_get_interface): Ditto. | |
| 2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |

| 2011-12-10 Werner Lemberg <wl@gnu.org> | |
| Add some variable initializations. | |
| Reported by Richard COOK <rscook@unicode.org>. | |

| earlier. | |
| 2011-12-08 Werner Lemberg <wl@gnu.org> | |
| Fix serious scaling bug in `FT_Get_Advances'. | |
| * src/base/ftadvanc.c (FT_Get_Advances): Advance values returned by | |

| 2011-12-08 Werner Lemberg <wl@gnu.org> | |
| * src/bdf/bdflib.c (_bdf_parse_start): Drop redundant error tracing. | |
| 2011-12-02 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| [mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH. | |
| Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON | |
| was a configurable macro to disable Carbon-dependent code. Because | |
| now configure script sets DARWIN_NO_CARBON by default and disables | |
| Darwin & Carbon-dependent codes, these macros can be unified. | |
| FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON | |
| (defined by default) is removed, because DARWIN_NO_CARBON violates | |
| FT_XXX naming convention of public macros, and a macro configured by | |
| default is not portable for the building without configure (e.g. | |
| make devel). | |
| * builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based | |
| old Mac font support is requested and Carbon is available. | |
| * builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support | |
| for Mac OS X without Carbon (e.g. Mac OS X 10.4 for ppc64) is | |
| requested. | |
| * include/freetype/config/ftconfig.in: Ditto. | |

| [apinames] Fix the overflow of signed integer hash. | |
| * src/tools/apinames.c (names_add): Change the type of `h' from | |
| int to unsigned int, to prevent undefined behaviour in the | |
| overflow of signed integers (overflow of unsigned int is defined | |
| to be wrap around). Found by clang test suggested by Sean | |
| McBride. | |

| [bdf] Fix Savannah bug #34896. | |
| ENCODING now covers the whole Unicode range. | |
| Note, however, that this change is quite expensive since it | |
| increases the size of three arrays by almost 400kByte in total. The | |
| right fix is to replace the logic with something smarter. | |
| Additionally, there exist very old BDFs for three-byte CCCII | |
| encoding which exceeds the range of Unicode (another reason to have | |
| a smarter logic). | |
| * src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod' | |
| arrays. | |

| [smooth] Slightly optimize conic and cubic flatterners. | |
| * src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic): Move | |
| out some code from the main loop to speed it up. | |
| 2011-09-11 Tomas Hoger <thoger@redhat.com> | |
| Slightly improve LZW_CLEAR handling. | |
| * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>: | |
| Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are | |
| handled as clear codes. This also re-sets old_code and old_char to | |
| predictable values, which is a little better than using `random' | |
| ones if the code following LZW_CLEAR is invalid. | |
| 2011-09-11 Tomas Hoger <thoger@redhat.com> | |
| Add explicit LZW decompression stack size limit. | |
| Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is | |
| constructed correctly. It's even less than that, see e.g. | |
| libarchive code comment for a better size upper bound: | |
| http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121 | |
| This patch adds explicit stack size limit, enforced when stack is | |
| realloced. | |
| An alternative is to ensure that code < state->prefix[code - 256] | |
| when traversing prefix table. Such check is less efficient and | |
| should not be required if prefix table is constructed correctly in | |
| the first place. | |
| * src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it. | |
| 2011-09-11 Tomas Hoger <thoger@redhat.com> | |
| Protect against loops in the prefix table. | |
| LZW decompressor did not sufficiently check codes read from the | |
| input LZW stream. A specially-crafted or corrupted input could | |
| create a loop in the prefix table, which leads to memory usage | |
| spikes, as there's no decompression stack size limit. | |
| * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First | |
| code in valid LZW stream must be 0..255. | |
| <FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent, | |
| code > free_ent is invalid. | |

| [ftstroke] Major revision. | |
| The main problems | |
| ----------------- | |
| o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter | |
| joins (not bevel joins) were generated. Indeed, the meanings of | |
| `miter' and `bevel' were incorrectly reversed (consistently) in | |
| both the code and comments. | |
| o The way bevel joins were constructed (whether specified | |
| explicitly, or created as a result of exceeding the miter limit) | |
| did not match what is required for stroked text in PostScript or | |
| PDF. | |
| The main fixes | |
| -------------- | |
| o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected. | |
| o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been | |
| introduced to support PostScript and PDF miter joins. | |
| o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an | |
| alias for FT_STROKER_LINEJOIN_MITER. | |
| Additionally, a variety of stroking errors have been fixed. These | |
| would cause various artifacts (including points `at infinity'), | |
| especially when stroking poor quality fonts. | |
| See | |
| http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html | |
| for example documents. The FreeType stroker now produces results | |
| very similar to that produced by GhostScript and Distiller for these | |
| fonts. | |
| Other problems | |
| -------------- | |
| The following problems have been resolved: | |
| o Inside corners could be generated incorrectly. Intersecting the | |
| inside corner could cause a missing triangular area and other | |
| effects. | |
| The intersection point can only be used if the join is between | |
| two lines and both lines are long enough. The `optimization' | |
| condition in `ft_stroker_inside' has been corrected; this | |
| requires the line length to be passed into various functions and | |
| stored in `FT_StrokerRec'. | |
| o Incorrect cubic curves could be generated. The angle | |
| calculations in `FT_Stroker_CubicTo' have been corrected to | |
| handle the case of the curve crossing the +/-PI direction. | |
| o If the border radius was greater than the radius of curvature of | |
| a curve, then the negative sector would end up outside (not | |
| inside) the border. This situation is now recognized and the | |
| negative sector is circumnavigated in the opposite direction. | |
| (If round line joins are being used, this code is disabled | |
| because the line join will always cover the negative sector.) | |
| o When a curve is split, the arcs may not join smoothly (especially | |
| if the curve turns sharply back on itself). Changes in | |
| direction between adjacent arcs were not handled. A round | |
| corner is now added if the deviation from one arc to the next is | |
| greater than a suitable threshold. | |
| o The current direction wasn't retained if a the outline contained | |
| a zero length lineto or a curve that was determined to be | |
| `basically a point'. This could cause a spurious join to be | |
| added. | |
| o Cubics with close control points could be mishandled. All eight | |
| cases are now distinguished correctly. | |
| Other improvements | |
| ------------------ | |
| o Borders for cubic curves could be too `flat'. | |
| FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent | |
| this. | |
| o The handling and use of movable points has been simplified a | |
| little. | |
| o Various values are now computed only if the results are actually | |
| needed. | |
| o The directions of the outer and inner borders have been swapped, | |
| as recommended by Graham Asher. | |

| * src/autofit/afindic.c (af_indic_metrics_init): Take AF_CJKMetric | |
| instead of AF_LatinMetric, and initialize as af_cjk_metrics_init. | |
| However bluezones are not initialized. | |
| (af_indic_metrics_scale): Take AF_CJKMetric instead of AF_LatinMetric. | |
| (af_indic_hints_init): Ditto. | |
| (af_indic_hints_apply): Ditto. | |
| * docs/CHANGES: Note about CJK bluezone support. | |

| 2011-05-04 Werner Lemberg <wl@gnu.org> | |
| * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Simplify. | |
| 2011-05-01 Just Fill Bugs <mozbugbox@yahoo.com.au> | |
| Werner Lemberg <wl@gnu.org> | |
| [autofit] Add more debugging functions. | |
| * src/autofit/afhints.c (af_glyph_hints_get_num_segments, | |

| 2011-05-01 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| Add new option `--disable-mmap' to configure script. | |
| * builds/unix/configure.raw: New option `--disable-mmap' | |
| is added. It is for the developers to simulate the systems | |
| without mmap() (like 4.3BSD, minix etc) on POSIX systems. | |

| [truetype] Always recalculate the sfnt table checksum. | |
| * src/truetype/ttobjs.c (tt_get_sfnt_checksum): Recalculate | |
| the sfnt table checksum even if non-zero value is written in | |
| the TrueType font header. Some bad PDF generators write | |
| wrong values. For details see examples and benchmark tests | |
| of the latency by recalculation: | |

| [truetype] Register a set of tricky fonts, NEC FA family. | |
| * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): | |
| Add 8 checksum sets for NEC FA family. For the tricky fonts | |
| without some tables (e.g. NEC FA fonts lack cvt table), | |
| extra check is added to assure that a zero-length table in the | |
| registry is not included in the font. | |

| [truetype] Fix a bug in the sfnt table checksum getter. | |
| * src/truetype/ttobjs.c (tt_get_sfnt_checksum): Check the | |
| return value of face->goto_table() correctly. | |
| 2011-04-28 Werner Lemberg <wl@gnu.org> | |
| [autofit] Improve tracing messages. | |
| * src/autofit/aflatin.c (af_latin_metrics_init_blues, | |
| af_latin_align_linked_edge, af_latin_hint_edges): Do it. | |
| 2011-04-25 Kan-Ru Chen <kanru@kanru.info> | |
| [truetype] Always check the checksum to identify tricky fonts. | |
| Because some PDF generators mangle the family name badly, | |
| the trickyness check by the checksum should be invoked always. | |
| For sample PDF, see | |
| http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00073.html | |
| * src/truetype/ttobjs.c (tt_check_trickyness): Even when | |
| tt_check_trickyness_family() finds no trickyness, | |
| tt_check_trickyness_sfnt_ids() is invoked. | |
| 2011-04-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
| [autofit] Add more Indic scripts with hanging baseline. | |
| * src/autofit/afindic.c (af_indic_uniranges): Tibetan, Limbu, | |
| Sundanese, Meetei Mayak, Syloti Nagri and Sharada scripts are | |
| added. | |
| 2011-04-21 Behdad Esfahbod <behdad@behdad.org> | |
| Always ignore global advance. | |
| This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant, | |
| deprecated, and ignored. The new behavior is what every major user | |
| of FreeType has been requesting. Global advance is broken in many | |
| CJK fonts. Just ignoring it by default makes most sense. | |
| * src/truetype/ttdriver.c (tt_get_advances), | |
| src/truetype/ttgload.c (TT_Get_HMetrics, TT_Get_VMetrics, | |
| tt_get_metrics, compute_glyph_metrics, TT_Load_Glyph), | |
| src/truetype/ttgload.h: Implement it. | |
| * docs/CHANGES: Updated. | |

| [autofit] Blur CJK stems if too many to preserve their gaps. | |
| When there are too many stems to preserve their gaps in the | |
| rasterization of CJK Ideographs at a low resolution, blur the | |
| stems instead of showing clumped stems. See | |
| http://lists.gnu.org/archive/html/freetype-devel/2011-02/msg00011.html | |
| http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00046.html | |
| for details. | |
| * src/autofit/afcjk.c (af_cjk_hint_edges): Store the position of | |
| the previous stem by `has_last_stem' and `last_stem_pos', and skip | |
| a stem if the current and previous stem are too near to preserve | |
| the gap. | |
| 2011-04-18 Werner Lemberg <wl@gnu.org> | |
| Integrate autofitter debugging stuff. | |
| * devel/ftoption.h, include/freetype/config/ftoption.h | |
| (FT_DEBUG_AUTOFIT): New macro. | |
| * include/freetype/internal/fttrace.h: Add trace components for | |
| autofitter. | |
| * src/autofit/aftypes.h (AF_LOG): Removed. | |
| (_af_debug): Removed. | |
| * src/autofit/*: s/AF_DEBUG/FT_DEBUG_AUTOFIT/. | |
| s/AF_LOG/FT_TRACE5/. | |
| Define FT_COMPONENT where necessary. | |
| 2011-04-18 Werner Lemberg <wl@gnu.org> | |
| Synchronize config files. | |
| * builds/unix/ftconfig.in: Copy missing assembler routines from | |
| include/freetype/config/ftconfig.h. | |
| 2011-04-13 Werner Lemberg <wl@gnu.org> | |
| [psaux] Fix Savannah bug #33047. | |
| Patch submitted by anonymous reporter. | |
| * src/psaux/psobjs.c (ps_table_add): Use FT_PtrDist for pointer | |
| difference. | |
| 2011-04-11 Kan-Ru Chen <kanru@kanru.info> | |
| Fix reading of signed integers from files on 64bit platforms. | |
| Previously, signed integers were converted to unsigned integers, but | |
| this can fail because of sign extension. For example, 0xa344a1eb | |
| becomes 0xffffffffa344a1eb. | |
| We now do the reverse which is always correct because the integer | |
| size is the same during the cast from unsigned to signed. | |
| * include/freetype/internal/ftstream.h, src/base/ftstream.c | |
| (FT_Stream_Get*): Replace with... | |
| (FT_Stream_GetU*): Functions which read unsigned integers. | |
| Update all macros accordingly. | |
| * src/gzip/ftgzip.c (ft_gzip_get_uncompressed_size): Updated. | |
| 2011-04-07 Werner Lemberg <wl@gnu.org> | |
| Update Unicode ranges for CJK autofitter; in particular, add Hangul. | |
| * src/autofit/afcjk.c (af_cjk_uniranges): Update to Unicode 6.0. | |
| 2011-04-04 Werner Lemberg <wl@gnu.org> | |
| Fix formatting of autofit debug dumps. | |
| * src/autofit/afhints.c (af_glyph_hints_dump_points, | |
| af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Adjust | |
| column widths. | |
| 2011-03-30 Werner Lemberg <wl@gnu.org> | |
| * src/autofit/aftypes.h (AF_OutlineRec): Removed, unused. | |
| 2011-03-24 Werner Lemberg <wl@gnu.org> | |
| * src/cff/cfftypes.h (CFF_MAX_CID_FONTS): Increase to 256. | |
| This limit is given on p. 37 of Adobe Technical Note #5014. | |
| 2011-03-23 Werner Lemberg <wl@gnu.org> | |
| * src/truetype/ttpload.c (tt_face_load_loca): Fix mismatch warning. | |
