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)
While
EBSC
says when to substitute one strike for another.
