This rule triggers for devices with an ABS_X/Y evaluators and no keyboard or multitouch events. There is no way we would ever add such a device as a pointer, keyboard or touch device anyway. A pointer device requires has_button (in which case the !has_key condtion would fail); a keyboard device would also mean !has_key is false and a touch screen device implies that !device->is_mt is false.
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.
