Alex:
Rotation is _very_ computationally expensive. If you don't rotate only
the visible portions of the bitmap(s), drawing is far to slow when
dragging the image. That's why I check for at least a 33Mhz DragonBallVZ
(fastEnough). Even with the 'visible part' limit, it's still way too slow
on 'less powerful' systems.

Ah, young webmaster...
java leads to shockwave.
Shockwave leads to realaudio.
And realaudio leads to suffering.
