26 * A specific kind of CullBin that sorts geometry in the order specified by
27 * the user-specified draw_order parameter. This allows precise relative
28 * ordering of two objects.
29 *
30 * When two or more objects are assigned the same draw_order, they are drawn
31 * in scene-graph order (as with CullBinUnsorted).
