	Is it possible to change individual pixels on an image
	without having to do XMapRaised each time ? Each map
	raise takes a long time, and we're trying to do pixel
	updates in real time.

	I think this will involve writing to the image memory
	directly, but I don't know if X provides a mechanism
	for doing so.

	Thanks in advance.
