The unsigned int font_seg variable which was (unfortunately) included in
some GDOS documentation does not belong there. It is an internal
variable which is only used by GDOS. Actual font headers on disk should
end after the "next_font" longword.
One other thing you should know about GDOS fonts... the font data is
NOT guaranteed to be contiguous with the end of the header. Whether on
disk or in memory, pointers/offsets are provided in the font header.
Use them! (Except the memory ones... you really should leave the
manipulation of font data loaded in memory up to the VDI...)
