I agree that we must come up with a working protocol soon, but I do not 
agree the one proposed was the best one.

I would prefer the current wl_surface interface to be extended that a 
new one created.
Adding a new interface is not the best performance-wise, and I see no 
reason why we would seperate these features
from wl_surface.

For programers having to cope with X and Wayland, and to better support 
the Present extension, I reiterate my suggestion
to do something similar to the X Present extension.
