With a quadro-4000M card under windows 7 64 bits, the glGetFramebufferAttachmentParameteriv calls in GetColorBufferSizes raise a GL_INVALID_ENUM.

I tried various tweaks (like not fixing attachment), to no avail.

It is the same graphics card for which I reported a non standard behaviour in 0015784, so it is definitely a flaky card, but the problem remains.

I modified the code to return 8-8-8-8 in case the glGetFramebufferAttachmentParameteriv calls fail, and everything now seems to be working fine on this machine.

I know it's ugly, but it's better than failing.
