    Remove calls to cogl_push_matrix() and cogl_pop_matrix().
    
    * examples/custom_actor/triangle_actor.c (do_triangle_paint):
    * examples/custom_container/examplebox.c (example_box_paint):
    Remove calls to cogl_push_matrix() and cogl_pop_matrix() that are
    apparently now unnecessary.
