Which of those is affected by the quirk? I think all of those except
r200 should be able to do GLSL, but you say r200 is the only one that
doesn't pass the tests. You may be able to convince me that this is a
good idea, but so far I don't think it's worth all the extra code.

You should only need one isinf() here, it's not supposed to care about the sign.

Is this intentional?
