You are right, of course. This is why I did all this point-movement in
my visual scroll routines. I don't know why I was thinking this would
work.

I tried to reproduce the slowdown on scrolling very large images, but
failed, which is good. But instead of working on those old scroll
routines, I'll first try your patches in bug #14567 and follow-up there
if necessary.
