Well, you'd be surprised what can be done with a cpu if you invest a level
of effort comparable to that needed to design a custom chip...  I've never
said that getting fast graphics out of a cpu could be done without a lot of
thought and experimentation.  Most code, running on most cpus, is "first
cut" code -- nobody has ever sat down and seriously thought about it for
a while to see if it could be made faster or better.  It is truly amazing
what can be accomplished if you really do this seriously.

But I admit that the point needs study beforehand.  Note, "study", not
preconceived notions that it has to be hardware because software is too slow.
