Would it help if the X server be made to remember the picture?
This is, mostly, what the pixmap does.
For
instance, is it possible to tell X that the letters are a layer over
the background image, which will be removed and replaced with new
ones? I assume the graphical 2D acceleration hardware has *some*
optimizations for these cases?
AFAIK, the current X protocol is too dumb for that. The Xv extension
may help. Imagine that, a binary editor that uses the video
extensions for a faster redisplay, Wow.
