Weston reference compositor

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.
