* clutter/clutter-color.c: (clutter_color_parse):
        Handle #rrggbbaa color setting strings (i.e with alpha).
        Set alpha to 0xff if it is not specified.

        * clutter/clutter-stage.c: (clutter_stage_get_actor_at_pos)
        Increase select buffer.

        * examples/super-oh.c:
        Fix up use of clutter_group_show_all()
