[mutter/wip/carlosg/clutter-seat: 43/43] backends: Move warp_pointer() to ClutterSeat

commit 61828e5e4cecbe48c7e56663bf314296e5ea1f60
Author: Carlos Garnacho <carlosg gnome org>
Date:   Wed Oct 9 18:01:34 2019 +0200

    backends: Move warp_pointer() to ClutterSeat
    
    The onscreen pointer sprite is a per-seat element, so it makes sense
    to move pointer warping over there too.
