We seem to access some structure that is located after the

FONTINFO. The FONTINFO documentation says that there may
|
|
follow some char-width table or font bitmap or vector info.
|

I think it is some kind of font bitmap that begins at offset 0x52,
|
|
as FONTINFO goes up to 0x51.
|
|
If this is correct, everything should be implemented correctly.
