When a surface is on a non-primary plane (overlay), we do not need to keep the GL texture up-to-date, since we are not using it. Avoid calling glTex(Sub)Image2D in that case, and accumulate the texture damage separately. This is especially useful for backends, that can put wl_shm buffers into overlays. The empty damage check has to be moved from surface_accumulate_damage() into gles2_renderer_flush_damage(), because it really needs to check the accumulated damage, not only the current damage. Otherwise, if a surface migrates from a plane to the primary plane, and does not have new damage, the texture would not be updated even for accumulated damage.

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.
