The Wayland back-end to the Weston compositor allows Weston to run inside an existing Wayland compositor, i.e. a nested Weston scenario or running Weston atop a completely different Wayland compositor. A set of 11 patches were published Sunday night for making the Wayland back-end more on par with the X11 back-end.
New features for Weston's Wayland back-end includes a proper frame with a close button, a Pixman/SHM fallback mode for acceleration, config parsing of Weston's output INI configuration sections, output transform support, and output scale support.
The patches also bring performance improvements and code clean-ups. A feature still missing though is full-screen support for the Wayland back-end, but that will come as part of a separate patch series.
These new Wayland back-end improvements for Weston were done by Jason Ekstrand and can be found for now on the wayland-devel list
