Like how we handle overlays, we split drm_output_set_cursor() into drm_output_prepare_cursor_surface() that will assign the hw cursor to a suitable surface and drm_output_set_cursor() that will do the actual work of updating cursor contents and moving it. This is more in line with how we handle everything else, and lets us update cursor contents based on changes to the cursor plane damage. This works when the cursor content changes but also accumulates damage when the cursor changes output. In that case we move the cursor surface to the cursor plane in the new output and weston_surface_move_to_plane() will generate the damage that triggers download of sprite contents there.
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.
