The colors do not work properly. From what I can tell by brief
observations from drawing a filled rectangle:

R = R
G = MIN(R, B)
B = MIN(R, G)
A = A

So the green and blue are switched AND they are clipped to red's
value. e.g., Red 0.5 and green 1 actually gives you red 0.5 and blue
0.5.

But maybe this is a problem with the graphics primitives?
