Screen Redraws (Surface Redraws, GPU Redraws) in Wayland

[Ryan Sipes]

Hey guys,

New to Wayland and had a big question. I was curious as to whether work 
had gone into when screen redraws were made (they are called "Surface 
Redraws" and "GPU Redraws" in Android). I know in Android this has 
resulted in better battery life. I'm sure many in this mailing list 
know, but what it does is only redraws when changes have been made. Is 
this on the roadmap? Has it already been implemented? I know it was on 
the roadmap for Mir, so I'm curious if it is an consideration in 
Wayland.

Love the work, using Wayland right now with multiple monitors and it 
works great!
