[RFC] wl_surface video protocol extension

[Axel Davy]

I think the simpler is to have a similar functionalities to the X 
Present extension:

git://people.freedesktop.org/~keithp/presentproto master


We can ask a buffer to be shown at a specific ust time, and we get the 
feedback at which ust
time it has hit the screen. And we could queue buffers.

It looks quite sane to me, and doing the same would help writing the 
support to the X Present extension.

It solves the problem you mentions, James Courtier-Dutton, since a Video 
Player that doesn't get their buffers back and know they didn't hit the 
screen, will understand it has to suspend, and will resume when it gets 
the feedbacks.
