Well....consider what the extension would require -- you would specify
the color at the corners of the screen. How is that different from
simply specifying colors for the 4 vertices of a rectangle?
Oh....and just because I've been there, if you try to do this with a
quad and you specify different vertex colors for all four verts,
different drivers can give you different results because they may
triangulate the quad differently.
