Copy-paste error sneaked ClutterTransformNodeClass in clutter_blit_node_class_init(). It wasn't problematic because they both typedef to ClutterPaintNodeClass, but fix it anyway. Also switch to g_object_ref() in clutter_blit_node_new(). Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1627>
