We should fix those tests to work correctly in the presence of alpha in
the visual. The system could have all visuals with alpha, and the test
should deal with it.
That said, I'd like to see some sanity in the PIGLIT_GL_VISUAL now that
we're not glut any more. The glut interface was awful and a total trap.
I think we should replace RGB | ALPHA with RGBA, and make RGB ask for
RGB and RGBA ask for RGBA.
