GL commands generating errors are ignored, with only a few exceptions. I.e., if
the GL driver would correctly handle the NaN, the effect should be the same as
what your patch does.

It's possible NaN is supposed to behave in a specific way in D3D, but that
would need some tests, and I suspect it's just undefined.
