[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,
SetSuperRound): Add parameter to handle the number of grid lines per
pixel.
(SET_SuperRound, ROUND_None, CUR_Func_round): Updated.

(Ins_ALIGNRP): Add tweak guard.
(Ins_IUP, Ins_DELTAP): Handle tweaks.
(Ins_GETINFO): Handle new ClearType bits.
(TT_RunIns): Handle tweaks.
* src/truetype/ttinterp.h: Updated.

(TT_ExecContextRec): Add members for subpixel hinting support.

FT_FREE() erases the duplicated pointers only and leave original

is invoked repeatedly. See Savannah bug #31040 for detail.

an error occurs in the bytecode interpretation. The interpretation
of invalid bytecode may break the function definitions and referring
them in later interpretation is danger. By unsetting these flags,
`fpgm' and `prep' tables are executed again in next interpretation.

`loadSize' and `loadStack'.

compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not
defined.
* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix
possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.
(finally!)
For most OpenType tables, `tt_face_load_xxxx' simply loads the table
and `face->root' is set later in `sfnt_load_face'. Here, we try to
make this work for _all_ tables.
* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
then exit. Error handling or setting face->root is done later in
`sfnt_load_face'.
Pretty trace messages.
* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
Mac bitmap-only fonts are not scalable.
Check that `face->header.Units_Per_EM' is not zero.
(LOAD_, LOADM_): Pretty trace messages.
* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics from
`eblc'.

(load_format_20, load_format_25, tt_face_get_ps_name): Use
face->max_profile.numGlyphs, instead of face->root.num_glyphs.

here.
(tt_slot_init): New function to create extra points for the internal
glyph loader. We then use it directly, instead of face's glyph loader,
when loading glyph.
* src/truetype/ttdriver.c: Use tt_slot_init for glyph slot
initialization.
(TT_Load_Glyph): Load flag dependencies are handled here.
Return error if size is NULL.
* src/truetype/ttgload.c: Heavy cleanup and refactor.
(TT_Hint_Glyph): New funcion to hint a zone, prepared by caller.
(TT_Process_Simple_Glyph): Use loader->pp's instead of recalculating.
Use TT_Hint_Glyph.
No need to save/restore loader->stream before/after
TT_Vary_Get_Glyph_Deltas now.
(TT_LOADER_SET_PP): New macro to calculate and set the four phantom points.
(TT_Process_Composite_Component, TT_Process_Composite_Glyph,
load_truetype_glyph): Refactor load_truetype_glyph into these three functions.
Never set exec->glyphSize to 0. (close #13107)
Forget glyph frame before calling TT_Process_Simple_Glyph.
(TT_Load_Glyph, load_sbit_image, tt_loader_init): Refactor TT_Load_Glyph into

Set various fields of `glyph' here, instead of in load_truetype_glyph
and compute_glyph_metrics.

`Activate' gray-scale specifing hinting within the TrueType
bytecode interpreter. This is an experimental feature which
should probably be made optional.
* src/truetype/ttgload.c (TT_Process_Simple_Glyph,
load_truetype_glyph): Move the code to set the pedantic_hinting flag
to...
(TT_Load_Glyph): Here.
Set `grayscale' flag except for `FT_LOAD_TARGET_MONO'.
* src/truetyep/ttinterp.c (Ins_GETINFO): Return MS rasterizer
version 1.7.
Return rotation and stretching info only if glyph is rotated or
stretched, respectively.
Handle grayscale info.
* src/truetype/ttinterp.h (TT_ExecContextRec): Add `grayscale'
member.

i.e. when a new family object was destroyed by an out-of-memory
condition during a glyph node initialization. The function
FTC_Cache_Lookup would flush the cache and restart the lookup
with a bad pointer.
