Anyone care to elaborate on how the mouse pointer gets there in the first
place? From what I've heard, the avg PC gfxcard doesn't have any sprites...
(Stooopid! Had we had sprites it would all be very simple, because sprites, by
definition, don't alter the background.)
I would (if I could, wanted to, etc.) go "bare metal", and draw picture,
pointer, whatever, myself from machine code. Appart from the simple "control
freak"-factor, (knowing what's actually happening) it prolly also avoids some
of the somewhat less than clever system routines...
Write logic in high-level, loops in metal...

This is the solution to a lot of problems!
As for the mouse pointer, it's not a problem, it's a symptom. I'm looking
forward to seeing some of the out-of-the-box graphics-engines in progress...
