Before this change, surface->clip would contain the region of this the surface that is obscured by opaque containing of other surfaces in any plane. If a surface was obscured only by a surface in another plane and the renderer was told to draw that region, the rendering would be clipped because of that. This patch changes the clip to be plane specific, so that it contains only the region of the surface obscured by other surfaces in the same plane. We also calculate a per plane clip, so that we don't tell the renderer to draw regions of the primary plane that are obscured by other planes. This damage remains on the primary plane until the its clip changes so that they are not obscured anymore.
Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for buiding weston and its dependencies.
