weston 9.0.0 Reference implementation of a Wayland compositor
Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right.
A Wayland compositor allows applications to render to a shared offscreen buffer using OpenGL ES. The compositor then culls the hidden parts and composes the final output. A Wayland compositor is essentially a multiplexer to the KMS/DRM Linux kernel devices.
