Just out of curiousity, why doesn't X under UNIX use the blitter?
It seems this would be a "selling point" for X/Unix on the Amiga over
the PC Unix boxes.  I mean, isn't this what the blitter chips are for?
Speeding up window systems like X?

Of course, I have heard that the X source is an absolutely monstrous
amount of C code. I imagine just getting the source to compile and work 
was a task in itself.
