list of possible formats https://msdn.microsoft.com/en-us/library/windows/desktop/bb173059%28v=vs.85%29.aspx
the ones marked BROKEN_PIXEL are not writing pixels properly, not knowing much
about pixel shaders, I'm not the best qualified to handle this
the ones marked UNTESTED means my Win8 machine doesn't support them
