reference Wayland compositor
Weston is the reference implementation of a Wayland compositor. It is a lean, fast compositor with a modular architecture supporting multiple backends (X11, Wayland, headless) and a plugin-based shell interface. It includes a set of demo and test clients demonstrating the Wayland protocol, as well as XWayland support for running X11 applications.
