[X window programs MUST be event-driven]

That was my response, too. Might as well program a Macintosh.

Unfortunately, you have to handle EXPOSE events.

Well, if X was a "real windowing system" (tm eddie caplan) the server would
recover the image from backing store (off-screen bitmaps, whatever).

Unfortunately X suffers from the Macintosh Syndrome... we'll make cuts in the
capability of the system to cram it into inadequate hardware and worry about
paying for it (in programmer time, poor matches to adequate hardware, and so
on) later on.
