	I'm not sure I understand your point.  Clearly *somebody* has to
	eventually make the image match the hardware.  You seem to suggest it

Not necessarily; there are many cases in which you simply get and put
pixmaps from the server without ever doing anything to them on the client.

Perhaps a quick and simple solution would be to provide conversion functions 
in Xlib that take an XImage and a desired format and do the conversion 
completely on the client side.
