This directory defines an image-stream abstraction which 
may originate in video hardware, or in a static image.

There are two video hardware implementations,
	One for the video boards on Sun ultra computers,
	the other for SGI equipment
		the SGI code is in a pretty sorry state,
		I had an easy time getting stuff to work
		on my INDY, but then when the push came
		for the MURI demo, I worked with Raphael,
		our ONYX, with SIRIUS video hardware.
		
		I had a pretty seriously awful time getting stuff to
		work at all on raphael, and the code is 
		currently a real crock.  It should be
		replaced with something cleaner and higher performing.


image-stream-test 
	is a program that can be used to test the video hardware
	interface.
