does this for images. It is not hard to implement, just replace the X
window in all X calls with the pixmap. The downside is that it uses up
more memory in the server.
I'm not sure what the point would be though -- emacs doesn't have any real problems with flicker etc (line-move aside, I'm assuming that's a temporary aberation until a better scheme for doing visual calculations is implemented).
If a better scheme is found, there is no point. The main point otherwise would be that the redisplay calculations could be made very simple, almost non-existant.
