Sometimes, if you're displaying quite a few sprites, you want it to appear as 
if all the sprites are drawn at once.  If you draw them individually, with 
enough of them, you'll get flicker.  So you draw everything to the gfx mem, 
then copy the gfx mem to the vid mem (usually by < ldir>).  If you really 
want to get advanced, you can change the vid port address ;)
