//       Class : DrawCullHandler
// Description : This special kind of CullHandler immediately draws
//               its contents as soon as it receives them.  This draws
//               geometry immediately as it is encountered in the
//               scene graph by cull, mixing the draw and cull
//               traversals into one traversal, and prohibiting state
//               sorting.  However, it has somewhat lower overhead
//               than separating out draw and cull, if state sorting
//               and multiprocessing are not required.
