Don't forget that sometimes X programs are run over a network link.
Smooth scrolling would be slow as hell if it has to be transfered over
that, even if it's 100 BaseT ethernet. It doesn't matter *what* you
use for graphics hardware in this case. And wouldn't double buffering
be *slower* over a network link? If you use standard X calls, only the
commands for those calls are transmitted, but if you use a buffer, you
have to send every pixel in the region over the link, right?
