Backends may move surfaces to different planes, in which case damage is generated in the primary plane. This damage is usually passed to the renderer, but in some cases the backend may decide to not render anything (that's the case when drm compositor scans out a client buffer). In that case the damage on the primary plane would be discarded, leading to artifacts later. This patch makes the backend's responsibility to clear the damage on the primary plane, so that unrendered damage is kept for as long as necessary.
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.
