And sprites are also very useful for certain things, at least one of which is really important... the mouse pointer. Now I know that other windowing systems get away with no hardware pointer, but you can always tell... the pointer flickers, is jumpy, and occasionally glitches, leaving little pointer-shaped turds on the screen. This is becoming less common, but I remember seeing it referred to in comp.windows.x in the past 6 months so it still happens even there. With a hardware pointer the programmer can ignore the stupid thing. -- Peter "Have you hugged your wolf today" da Silva `-_-' ...texbell!sugar!peter, or peter@sugar.hackercorp.com 'U` ``Back off dude!
