When we analyze and accumulate damage prior to repainting, we need to accumulate damage per plane, so that whatever damage a surface contributes is accumulated in the plane that it's assigned to. Before, we would always accumulate damge in the primary plane, which caused repaints in the primary plane whenever a surface in a sprite or framebuffer was damaged. Eliminating this repaint is a big win for cases where we pageflip to a client surface or use a sprite overlay. This also prepares for fixing the missing cursor updates, since we now track damage to the cursor surface in a dedicated sprite plane.
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.
