* src/pfr/pfrsbit.h, src/pfr/pfrsbit.c, src/pfr/pfrload.c,

        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.
