2429dc3d	2013-06-03T12:41:58	Add CFF_CONFIG_OPTION_OLD_ENGINE configuration option. This controls whether the old FreeType CFF engine gets compiled into FreeType. It is now disabled by default. * devel/ftoption.h, include/freetype/config/ftoption.h (CFF_CONFIG_OPTION_OLD_ENGINE): New macro. * src/cff/cffdrivr.c (cff_property_set), src/cff/cffgload.c (CFF_Operator, cff_argument_counts, cff_builder_add_point, cff_operator_seac, cff_decoder_parse_charstrings, cff_slot_load), src/cff/cffgload.h, src/cff/cffobjs.c (cff_driver_init): Use CFF_CONFIG_OPTION_OLD_ENGINE to guard the affected code. * docs/CHANGES: Updated.
760d342d	2013-05-29T11:36:18	Add support for color embedded bitmaps (eg. color emoji). A new load flag, FT_LOAD_COLOR, makes FreeType load color embedded-bitmaps, following this draft specification https://color-emoji.googlecode.com/git/specification/v1.html which defines two new SFNT tables, `CBDT' and `CBLC' (named and modeled after `EBDT' and `EBLC', respectively). The color bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA pre-multiplied sRGB images. If PNG support is available, PNG color images as defined in the same proposed specification are supported also. Note that color bitmaps are converted to grayscale if client didn't ask for color. * builds/unix/configure.raw: Search for libpng. Add `--without-png' option. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_PNG): New macro. * include/freetype/freetype.h (FT_LOAD_COLOR): New load flag. * include/freetype/ftimage.h (FT_Pixel_Mode): Add `FT_PIXEL_MODE_BGRA'. * include/freetype/tttags.h (TTAG_CBDT, TTAG_CBLC): New tags. * src/base/ftbitmap.c (FT_Bitmap_Embolden): Updated.

77c39b1d	2013-05-04T18:04:07	[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'. * src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues, cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated. * src/cff/cf2blues.c (cf2_blues_init): Updated.
94152819	2013-05-04T16:40:12	More fixes for clang's `sanitize' feature. * src/base/ftcalc.c (FT_DivFix): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate, FT_Vector_Length, FT_Vector_Polarize): Ditto. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Simplify. * src/cff/cffload.c (cff_subfont_load): Fix constant. * src/cff/cffparse.c (cff_parse_integer, cff_parse_real, do_fixed, cff_parse_fixed_dynamic): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/cid/cidload.c (cid_get_offset): Ditto. * src/psaux/psconv.c (PS_Conv_ToFixed): Ditto. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto. * src/truetype/ttinterp.c (TT_MulFix14, TT_DotFix14): Ditto.

(FT_INT8_, FT_BYTE_I16, FT_BYTE_I32, FT_INT8_I16, FT_INT8_I32, FT_INT8_I32, FT_INT8_U32): Removed. (FT_PEEK_SHORT, FT_PEEK_LONG, FT_PEEK_OFF3, FT_PEEK_SHORT_LE, FT_PEEK_LONG_LE, FT_PEEK_OFF3_LE): 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.
99033fef	2013-05-03T17:39:24	* src/cff/cf2blues.c: Remove dead code.
9bf75e08	2013-05-02T11:09:15	* src/cff/cffgload.c: Include FT_CFF_DRIVER_H.
06474c3e	2013-04-13T18:53:28	[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.
283c8ed8	2013-04-13T15:02:31	[cff] New files for Adobe's Type 2 interpreter and hinting engine.
831dac88	2013-04-12T21:13:49	[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.
2dc26621	2013-04-12T20:11:38	Add output bitmap checksums. Use `FT2_DEBUG=bitmap:3' for tracing. * src/base/md5.c, src/base/md5.h: New files, taken from 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.
fc185ef4	2013-04-12T19:48:06	Add framework for CFF properties. * include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC7): New macro. * src/cff/cffdrivr.c: Include FT_SERVICE_PROPERTIES_H. (cff_property_set, cff_property_get): New function, still empty. Define `cff_service_properties' service. Update `cff_services'. * src/cff/cffpic.h: Include FT_SERVICE_PROPERTIES_H. (CFF_SERVICE_PROPERTIES_GET): New macro. CffModulePIC: Add `cff_service_properties'.
04e547bd	2013-04-03T07:37:56	Fix Savannah bug #38589. * src/bdf/bdflib.c (_bdf_readstream): Thinko.
762bf19a	2013-03-24T08:37:12	Typo.
eed83061	2013-03-23T14:25:43	Whitespace.
fbb0773c	2013-03-23T14:06:54	[autofit] Minor. * src/autofit/afmodule.c (af_property_set): Typo. (af_autofitter_init, af_autofitter_done): Use cast.
b114b7c0	2013-03-17T22:42:07	Fix Savannah bug #38538. * builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c, builds/wince/ftdebug.c (FT_Throw): Add function.
5ea06ce0	2013-03-17T08:14:46	Whitespace.
706fc833	2013-03-17T08:09:17	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.
8b4459b8	2013-03-17T07:44:35	* src/pshinter/pshpic.h (GET_PIC): Use correct container.
89f50647	2013-03-14T17:50:49	/: 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.
e3c93015	2013-03-14T11:21:17	/: Use FT_Err_Ok only. This is a purely mechanical conversion.
059bc335	2013-03-14T10:27:35	/: 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.
c58ce3be	2013-03-13T11:06:39	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.
dbc6e3f1	2013-03-12T11:42:20	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.
c879f245	2013-03-11T10:11:57	[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'.
d6bc524b	2013-03-11T09:50:53	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.
2d882540	2013-03-08T21:23:45	[cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also. * src/cff/cffgload.c (cff_slot_load): Implement it.
2ba18ba1	2013-02-22T23:58:57	[base] Fix commit ab02d9e8. * src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22.
f9434dba	2013-02-19T21:27:18	[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.
0e536676	2013-02-18T20:41:56	[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.
a2c7eb18	2013-02-07T19:49:12	* 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.
bfcc375b	2013-02-06T08:47:29	* 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.
00dfa330	2013-02-05T19:23:16	[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).
0eb6316f	2013-02-01T20:24:00	[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.
30f1e6ca	2013-02-01T14:50:08	Fix Savannah bug #38221. This complements commit 83c0ebab. * src/base/ftcalc.c (FT_MulDiv_No_Round): Don't enclose with `TT_USE_BYTECODE_INTERPRETER'.
40633205	2013-02-01T12:55:44	[truetype] Fix Savannah bug #38211. * src/truetype/ttinterp.c (Ins_IP): Make FreeType behave identical to other interpreters if rp1 == rp2 (which is invalid).
fba917d0	2013-01-30T20:14:18	Improve comments.
d56e544d	2013-01-28T22:29:51	Add an important comment. Thanks to Hin-Tak Leung for the analysis.
6b9034f0	2013-01-28T13:56:23	Formatting, comment improvements.
ab02d9e8	2013-01-28T06:35:19	[base] Small optimization of BBox calculation. * src/base/ftbbox.c (BBox_Cubic_Check): Use FT_MSB function in scaling algorithm.
c574d72c	2013-01-26T17:40:44	[truetype] Minor formatting fix.
97ba5109	2013-01-26T17:05:40	[truetype] Fix rasterizer_version logic in sph.

610ee58e	2013-01-25T23:33:00	[base] Fix broken emboldening at small sizes. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Do not attempt to normalize zero-length vectors.
f41ee054	2013-01-25T16:41:24	Fix Savannah bug #38167. This fixes commit 83c0ebab from 2012-06-27. * src/truetype/ttinterp.h: s/TT_CONFIG_OPTION_BYTECODE_INTERPRETER/TT_USE_BYTECODE_INTERPRETER/.
ba931be2	2013-01-25T00:57:09	[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.

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

0e0fdc5d	2013-01-12T23:05:55	[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.
081aba39	2013-01-12T22:36:37	[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. * src/truetype/ttinterp.c (Normalize): Remove error compensation. (TT_VecLen): Remove any mention of old less accurate implementation.

b4ac30b0	2013-01-02T22:21:37	[base] Reduce trigonometric algorithms. After we get within 45 degrees by means of true 90-degree rotations, we can remove initial 45-degree CORDIC iteration and start from atan(1/2) pseudorotation, reducing expansion factor thereby. * src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macros.

d7383b7b	2012-12-20T01:03:22	[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 values. (ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Remove initial rotation.

Add support for color embedded bitmaps (eg. color emoji). A new load flag, FT_LOAD_COLOR, makes FreeType load color embedded-bitmaps, following this draft specification https://color-emoji.googlecode.com/git/specification/v1.html which defines two new SFNT tables, `CBDT' and `CBLC' (named and modeled after `EBDT' and `EBLC', respectively). The color bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA pre-multiplied sRGB images. If PNG support is available, PNG color images as defined in the same proposed specification are supported also. Note that color bitmaps are converted to grayscale if client didn't ask for color. * builds/unix/configure.raw: Search for libpng. Add `--without-png' option. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_PNG): New macro. * include/freetype/freetype.h (FT_LOAD_COLOR): New load flag. * include/freetype/ftimage.h (FT_Pixel_Mode): Add `FT_PIXEL_MODE_BGRA'. * include/freetype/tttags.h (TTAG_CBDT, TTAG_CBLC): New tags. * src/base/ftbitmap.c (FT_Bitmap_Embolden): Updated.

[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'. * src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues, cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated. * src/cff/cf2blues.c (cf2_blues_init): Updated.

[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'.

2013-03-13T11:06:39

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.

2013-02-06T08:47:29

* 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.

[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'. * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_image): Implement it.

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

[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.

[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. * src/truetype/ttinterp.c (Normalize): Remove error compensation. (TT_VecLen): Remove any mention of old less accurate implementation.

[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 values.
