Just wanted to add that this would fix the fixed function Z vs specular color 
alpha selection with table and vertex fog. Vertex shaders seem to be treated 
as transformed vertices.

That said, the way the fixed function pipeline uses was developed by looking 
at what games need. The patch Vitaly sent looks good to me, but if there are 
any regressions I will have to try to write a unit test(though it will be 
tricky due to the pixel exactness thingy)
