    Use meta_actor_painting_untransformed() for MetaShapedTexture
    
    The old check for using NEAREST by checking clutter_actor_is_in_clone_paint()
    and meta_actor_is_untransformed (actor) doesn't work properly since
    clutter_actor_is_in_clone_paint() does not look at ancestors of the
    actor; it only applies to a direct clone of the actor. Using
    meta_actor_painting_untransformed() allows us to check exactly what we
    care about rather than using tricky approximations.
