The MACs graphics and characters are all memory mapped. Character may be
drawn from vector "maps" or "templates" but its still bit-mapped
graphics. The MAC doesn't contain any special hardware designed for explicit
vectored graphics. Only a few manufacturers still make things like that
(HP, Tektronix, etc.) for scopes and special displays (radar, string
modeling, etc. What you are seeing on the MAC is software and software
on the MAC or PC can be done better and faster. And I don't see the
connection between an application program and a facility for drawing a
given character set. FACTS please.
