There are many reasons. The most important routines still need to be 
written in assembler (only one out of 4 is). I have only rearranged the 
oberon code a bit to make the compiler produced code faster. (Asm 
would still gain more than a factor of 4 with MMX).

Semi-transparency is very slow to calculate (do you have a 
MMX enabled processor ?)

The only two things that are slower are filtered-zooming and
(slowest) semi-transparent-filtered-zooming.

Maybe I will reduce the quality while dragging windows. This will help
much in zoomed situations.
