Then again, this probably is about a redirected window... so really it
isn't the textured video rendering that needs to be synchronized to the
refresh, but the compositing manager's rendering to the screen. A
hackish solution could be to use the WAIT_UNTIL trick for all rendering
targeted to the screen pixmap; a possibly cleaner solution could be to
create SYNC extension counters for vertical blank and make the
compositing manager use those.
