Version 2 is faster than Version 1.0.1 in just about every way
imaginable.  Using x11perf and our own NeWS benchmarks, we found
increases from a few percent up to 32X improvement on SPARCstations
with dumb 8 bit color framebuffers (CG3).  GX graphics improvements
were even higher.  A fair ballpark estimate is, graphics are twice as
fast on average, and window manipulation is 5X faster.
