[PATCH 0/4 v2] add resize support for wl_surface

[Zhao Halley]

overlay plane supports rendering with resize, while wayland protocol 
doesn't have interface for it yet. so I go ahead to add it and ask for 
your comments.
this interface also has potential benefit for memory footprint: 
for example: when surface size is bigger than original content (an image 
maybe), client needn't create a new buffer to scale it, but depending
on weston to handle it.

basing on it, I would like add more policy on how to assign a surface to
overlay plane. for example, the surface with following attribute should 
have a higher priority to render to overlay plane:
    YUV format (YUYV indeed for GEN gfx)
    render with scaling required
    surface update with a higher frequency
    surface has other surfaces behind it

these patches include 3 parts:
    1. wayland protocol file update
    2. weston update to support new api
    3. test case update (test case in $mesa/test2/wayland-drm, the case hasn't commited to upstream yet)
        http://lists.freedesktop.org/archives/mesa-dev/2012-June/022544.html

update:
    use wl_surface_attach2 instead of wl_surface_damage2

  test purpose:       filter out background/cursor/shell surface      
    disable geometry transform for overlay
