Werner Lemberg c58ce3beee 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.

Werner Lemberg dbc6e3f192 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.

Werner Lemberg 2ef0a19842 [type1] Fix handling of /FontBBox in MM fonts.
Problem reported by Del Merritt <del@alum.mit.edu>

If we have

  /FontBBox { { 11 12 13 14 15 16 17 18 }
              { 21 22 23 24 25 26 27 28 }
              { 31 32 33 34 35 36 37 38 }
              { 41 42 43 44 45 46 47 48 } }

in the /Blend dictionary,  then the first BBox is { 11 21 31 41 },
the second { 12 22 32 42 }, etc.

* include/freetype/internal/psaux.h (T1_FieldType): Add
`T1_FIELD_TYPE_MM_BBOX' (for temporary use).

* src/psaux/psobjs.c (ps_parser_load_field) <T1_FIELD_TYPE_MM_BBOX>:

Werner Lemberg a9f6f85e77 Various compiler warning fixes.
* include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Use
`logical not' operator instead of negation.  The idea is that `~'
returns exactly the data type enforced by the cast to a pointer (be
it 32bit or 64bit or whatever), while a negative integer has not
this flexibility.

Infinality ed6508c41a [truetype] Remove unused rounding functionality. 2012-06-26 17:20:27 -05:00
Infinality 79e36baebb [truetype] Support subpixel hinting.
This is the large, famous `Infinality' patch to support ClearType
bytecode which has been available from
http://www.infinality.net/blog/ for some time, and which has been
refined over the last years.  While still experimental, it is now
mature enough to be included directly into FreeType.

Most of the code is based on the ClearType whitepaper written by
Greg Hitchcock

  http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx

which gives a detailed overview of the necessary changes to the
Microsoft rasterizer so that older fonts are supported.  However, a
lot of details are still missing, and this patches provides a
framework to easily handle rendering issues down to the glyph level
of certain fonts.

Note that ClearType support is not completely implemented!  In
particular, full support for the options `compatible_widths',
`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
instruction) is missing.

* src/truetype/ttsubpix.c: New file, providing code to handle
`tweaks', this is, rules for certain glyphs in certain fonts
(including wildcards) which need a special treatment.

* src/truetype/ttsubpix.h: New file, holding the tweaking rules.

* include/freetype/config/ftoption.h, src/devel/ftoption.h
(TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro.

* include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID,
FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros.

* src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include
`ttsubpix.c'.

* src/truetype/ttgload.c: Include `ttsubpix.h'.
[All changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

(tt_get_metrics): Set tweak flags.
(TT_Hint_Glyph): Call `FT_Outline_EmboldenXY' if necessary.
(TT_Process_Simple_Glyph): Compensate emboldening if necessary.
(compute_glyph_metrics): Handle `compatible widths' option.
(tt_loader_init): Handle ClearType GETINFO information bits.

* src/truetype/rules.mk (TT_DRC_SRC): Updated.

* src/truetype/ttinterp.c: Include `ttsubpix.h'.
[Where necessary, changes below are guarded by
TT_CONFIG_OPTION_SUBPIXEL_HINTING.]

(Direct_Move, Direct_Move_X): Extended.
(Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid,
Round_Up_To_Grid, Round_To_Double_Grid, Round_Super, Round_Super_45,
