patch

There's no reason for the Web process to paint faster than the UI process
can apply to and commit the CoreAnimation layer tree.

Also, once we get proper double-buffering and purgeable back buffers, we
will need the ability to make some assumptions about in-use surfaces.

Unfortunately, we can't actually tell when the render server commits, 
as this is an asynchronous operation in a process we don't control, so
for now, this is only an approximation.

This also means that the assumptions we would like to make won't be
strong guarantees yet.
