Øyvind Kolås 53ec33f34c * clutter/clutter-main.[ch]: added clutter_grab_pointer,
clutter_ungrab_pointer and clutter_get_pointer_grab, in
clutter_do_event deliver pointer related events only to the
actor with the pointer grab if a grab exists.
* clutter/clutter-private.h: added pointer_grab_actor to context.
* tests/Makefile.am:
