* src/pfr/pfrsbit.h, src/pfr/pfrsbit.c, src/pfr/pfrload.c,
src/pfr/pfrgload.c, src/pfr/pfrobjs.c, src/pfr/pfrtypes.h,
Jamfile, src/base/ftobjs.c: adding support for embedded bitmaps to
the PFR driver, and rewriting its kerning loader / handler to use all
kerning pairs in a physical font (and not just the first item).
* src/tools/docmaker/content.py, src/tools/docmaker/sources.py,
src/tools/docmaker/tohtml.py: fixing a few nasty bugs
* src/sfnt/ttcmap0.c: the validator for format 4 sub-tables is
now capable of dealing with invalid "length" fields at the start
of the sub-table. This allows fonts like "mg______.ttf" (i.e.
Marriage) to return accurate charmaps.
* docs/CHANGES: updating
Adding support for embedded bitmaps to the PFR driver, and rewriting
its kerning loader/handler to use all kerning pairs in a physical
font (and not just the first item).
* src/pfr/pfr.c: Include `pfrsbit.c'.
* src/pfr/pfrgload.c: Include `pfrsbit.h'.
* src/pfr/pfrload.c (pfr_extra_item_load_kerning_pairs): Rewritten.
(pfr_phy_font_done, pfr_phy_font_load): Updated.
* src/pfr/pfrobks.c: Include `pfrsbit.h'.
(pfr_face_init): Handle kerning and embedded bitmaps.
(pfr_slot_load): Load embedded bitmaps.
(PFR_KERN_INDEX): Removed.
(pfr_face_get_kerning): Rewritten.
* src/pfr/pfrsbit.c, src/pfr/pfrsbit.h: New files.
* src/pfr/pfrtypes.h (PFR_KernItemRec): New structure.
(PFR_KERN_INDEX): New macro.
(PFR_PhyFontRec): Add items for kerning and embedded bitmaps.
* src/pfr/Jamfile (_sources) [FT2_MULTI]: Add `pfrsbit'.
* src/base/ftobjs.c (FT_Load_Glyph): Don't load bitmap fonts if
FT_LOAD_NO_RECURSE is set.
Load embedded bitmaps only if FT_LOAD_NO_BITMAP isn't set.
* src/tools/docmaker/content.py, src/tools/docmaker/sources.py,
src/tools/docmaker/tohtml.py: Fixing a few nasty bugs.
* src/sfnt/ttcmap0.c (tt_cmap4_validate): The validator for format 4
sub-tables is now capable of dealing with invalid "length" fields at
the start of the sub-table. This allows fonts like "mg______.ttf"
(i.e. Marriage) to return accurate charmaps.
* docs/CHANGES: Updated.
