Now that MetaShapedTexture is a ClutterContent implemetation that is aware of its own buffer scale, it is possible to simplify the event translation routines. Set the geometry scale in MetaSurfaceActor, and stop adjusting the surface scale when translating points. Also remove the now obsoleted meta_wayland_actor_surface_calculate_scale() function. https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
