[PATCH 5/5] present: When unflipping, copy to flip window rather than screen

[Keith Packard]

unflip happens after the clip lists have been updated, so instead of
smashing the whole screen and drawing over other windows, just draw to
the original flip window; it'll have the right clip list and so the
copy will work just fine.
