Xv: scrap overlay offscreen pixmap support
The code looks like it's been bitrotting since being copied over from the i810 driver. Furthermore painting rgb pixmaps with the overlay engine is in these days of modern compositing X an absolute no-go. And textured video doesn't support it neither, so its likely never ever used by applications. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Eric Anholt <eric@anholt.net>
