Just FYI classic swrast suffers from this issue, and since I added front buffer
support to softpipe/llvmpipe they now also.

We try to call XGetImage when no window has been mapped, and the X server
correctly throws BadMatch. I'm not sure how to detect this is going to
fail in this
case, as I don't think inside libGL I can detect the unmapped front buffer.
