//       Class : CullBinFixed
// Description : A specific kind of CullBin that sorts geometry in
//               the order specified by the user-specified draw_order
//               parameter.  This allows precise relative ordering of
//               two objects.
//
//               When two or more objects are assigned the same
//               draw_order, they are drawn in scene-graph order (as
//               with CullBinUnsorted).
