00024 //       Class : DrawCullHandler
00025 // Description : This special kind of CullHandler immediately draws
00026 //               its contents as soon as it receives them.  This draws
00027 //               geometry immediately as it is encountered in the
00028 //               scene graph by cull, mixing the draw and cull
00029 //               traversals into one traversal, and prohibiting state
00030 //               sorting.  However, it has somewhat lower overhead
00031 //               than separating out draw and cull, if state sorting
00032 //               and multiprocessing are not required.
