src/cache/ftcbasic.c, src/cache/ftccmap.c, src/cache/ftccache.c,
src/cache/ftcglyph.c, src/cache/ftcimage.c, src/cache/ftcmanag.c,
src/cache/ftcmru.c, src/cache/ftcsbits.c, src/cache/rules.mk:
make various fields of the @FTC_ManagerRec structure private, i.e.
un-accessible from client applications, introducing the new private
"src/cache/ftcint.h" header
* include/freetype/cache/ftcmru.h, src/cache/ftcmru.c: implement
the new convenience function FTC_MruList_RemoveOldest()
ttmetrics here. TrueType fonts with only sbits always have
ttmetrics.valid set to false.
* src/truetype/ttgload.c (TT_Load_Glyph): Check that ttmetrics is
valid before loading outline glyph.
* src/cache/ftcimage.c (FTC_INode_New): Fix a memory leak.
TT_Done_Context and rename TT_Destroy_Context to TT_Done_Context with
slight changes.
* src/truetype/ttobjs.h (tt_slot_init): New function.
* src/truetype/ttobjs.c (tt_driver_init): Initialize execution context
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
these three functions.
Set various fields of `glyph' here, instead of in load_truetype_glyph
and compute_glyph_metrics.
* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): New functions.
(tt_size_init): Add 4, instead of 2, (phantom) points to twilight zone.
Move code that runs fpgm to tt_size_run_fpgm.
(Reset_Outline_Size): Move code that runs prep to tt_size_run_prep.
(tt_glyphzone_new): Allocate right size of arrays.
Set max_points and max_contours properly.
removing compiler warnings (Visual C++ /W4)
* Jamfile, src/otvalid/{otvcommn.h,otvgdef.c,otvgpos.c,otvgsub.c,
otvjstf.c}: modified the code to use a different pre-processor trick
to implement the OTV_NEST1, OTV_NEST2 and OTV_NEST3 macros. The code
now compiles neatly with Visual C++. The 'otvalid' module has been
put in the Jamfile build again.
ft_glyphslot_grid_fit_metrics.
* src/truetype/ttgload.c (compute_glyph_metrics): Use
ft_glyphslot_grid_fit_metrics.
* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
(cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Use
ft_glyphslot_grid_fit_metrics.
FT_Outline_Get_CBox is called twice.
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Modify metrics to more
reasonable values when emboldening outline glyphs. The theoretic
ones are unrealistic.
