The old version of the test assumed the glTexCoord call was being properly used in the system. However, at least in mesa, it is easy for an implementation to ignore the given coordinate. Thus setup the texture and texture coordinate to ensure it is respected. --- As before, I don't have commit rights. I think this test case is right, but I don't have a conforming OpenGL implementation to double check.
