[PATCH 0/4] add resize support for wl_surface damage

[Zhao, Halley]

Hi Kristian:
I had a short talk with pq in IRC, he think scaling is a fundamental change to wayland core protocol, it impacts the coordinate system of wl_surface.
Your feedback is required to move it on.

First of first, do you think resize should happen for wayland server(Weston)?
Then, if yes, what's your opinion on the interactions between different parts of the protocol when we change the coordination?
Thanks.
