Well, this might be true, but that's no reason to disallow it - it's 
still a little useful...  and we need to test vertex shaders first, 
before we get to pixel shaders.
Implementing software pixel shaders is significantly more difficult 
(because it requires rasterizer, and the speed issue is much more 
important).
