Well, there isn't any public spec for this, or most parts of the Win32 API
really, so in that regard it's always hard to say what's valid and what isn't.
What we've always cared about is applications, and failing these tests means
breaking them. For example, exp_test is for bug 27850, and IIRC failing the rcp
and rsq ones would break Battlefield 1942.

I wish anyones who wants to try that good luck, but my experience it pretty
much that if you want something fixed you need to do it yourself, with very few
exceptions.

Every time I write a new test, it seems more and more tempting to either just
skip the D3D tests completely on anything that isn't AMD or NVIDIA, or to just
stop writing new tests.
