48 We seem to access some structure that is located after the
49 FONTINFO. The FONTINFO documentation says that there may
50 follow some char-width table or font bitmap or vector info.
51 I think it is some kind of font bitmap that begins at offset 0x52,
52 as FONTINFO goes up to 0x51.
53 If this is correct, everything should be implemented correctly.
