Note that I didn't say there weren't fast bit
blitters if you just look at some spec sheet about
how fast the hardware can run in some cases
the hardware does well.  The point is that
THEY USUALLY DON'T DO ALL THE CASES!!
Making up for the boundary conditions
in software is often slower than just doing it
with the CPU in the first place.  

And as for the speed of a 68K, my Macintosh
can paint rings around my SUN 3/160.  Maybe
it is the cruft getting to the pixrects,
but the end result is that my Macintosh
paints windows much faster per unit area.
And having seen an SE do it, it does it
faster than our SUN 3/260.
