  Plus, it's much faster.  With 25 mhz 030s (GVP, A3000s), you can beat
the blitter using the processor for lines and polygon fills (30% and 100%
faster, respectively).  A3000s are even faster if you use 32 bit writes
to chip ram. I achieved a 25% improvement on the A3000 over the A2000 w/030.
I haven't tried comparing 32 bit block copies against the blitter, perhaps
someone out there has...
