    Revert "windows opengl: Set PFD_DOUBLEBUFFER even for single buffer rendering"
    
    This reverts commit 6fd7199230bfc81d6aadf53b3c115def8caba90c. Kendy says the
    original problem can't be reproduced anymore, and most unexpected flickering
    goes away with this for my nvidia card.
    
    Also, it's a good idea in general to keep PFD_DOUBLEBUFFER and
    WGL_DOUBLE_BUFFER_ARB in sync, which is now the case.
