Currently the core input code does surface picking before calling into the focus callback of the current grab. Not all grabs need to pick a surface however, so we're doing work we don't have to in those cases. For example, the shell move and resize grabs don't need to pick and the default grab in implicit grab mode doesn't either. With this change, the pointer grab mechanism is now very simple: the focus callback is called whenever the pointer may have a new focus, the motion callback is called whenever the pointer moves and the button callback whenever a button is pressed or released.
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.
