    app: use gimp:normal instead of gegl:over in gimp_gegl_apply_cached_operation()
    
    When the operation doesn't have an input pad, composite it over the
    input using gimp:normal, instead of gegl:over, for consistency with
    the rest of our compositing code (although the result should be the
    same).
