Well there are a variety of tables that could relate to bitmaps
   GSUB  to tell you when to use ligature glyphs, etc.
   GPOS  to tell you about kerning, etc.

But the data describing the glyph images themselves are in
   EBLC         (bloc on a mac)
   EBDT         (bdat on a mac)
says when to substitute one strike for another.
