Sometimes the latest and sometimes an earlier is best. I am not sure
this can be decided best in flip_page. better would be at a higher
level.

Vdpau is missing a cancel queued surface, so it is not easy to remove an
already queued surface from the presentation queue - if we wanted to
drop an earlier frame.
