Hmmm, yes, I didn't think of that. However, wouldn't a global pixmap
cache solve the same problem in a more general way? For example, the
server would scan the screen for patterns that tend to repeat, and then
send them to the client only once, thereafter sending only a reference
number. Things like font characters, window borders, buttons, icons,
etc. could then all be saved at the client, and the server would only
send their arrangement.
