* post_parse vfunc because that's the point where we connect to a compositor
* and that's also the point where we will be notified of input devices so we
* need the device-manager to exist early on.
*
* To be consistent with other clutter backends though we only associate the
* device manager with the backend when _clutter_events_wayland_init() is
* called in _clutter_backend_init_events(). This should still allow the
* runtime selection of an alternative input backend if desired and in that
* case the wayland device manager will be benign.
*
* FIXME: At some point we could perhaps collapse the
* _clutter_backend_post_parse(), and _clutter_backend_init_events()
* functions into one called something like _clutter_backend_init() which
* would allow the real backend to manage the precise order of
* initialization.
