Another method for drawing characters to the screen (and quite legal) is 
to predraw the
the characterset into an offscreen buffer and use copybits to blast their 
images to screen.
This is what Red Ryder does. It is very fast because in the long run 
DrawString and DrawChar
both call copybits eventually. If your character set is a mono-spaced font 
you can use the
byte itself as an index into the offscreen bitmap.
