Add Rage 128 pageflipping support, defaults to off. DRM version bump to

    2.5.0. It still has some issues, including a flicker in the fps meter
    in tuxracer and I've seen garbage left behind after moving/closing
    windows. However, it's usable. Add the Option "EnablePageFlip" "YES" to
    use it.
