00032 //       Class : SceneGraphAnalyzerMeter
00033 // Description : This is a special TextNode that automatically updates
00034 //               itself with output from a SceneGraphAnalyzer instance.
00035 //               It can be placed anywhere in the world where you'd like
00036 //               to see the output from SceneGraphAnalyzer.
00037 //
00038 //               It also has a special mode in which it may be
00039 //               attached directly to a channel or window.  If this is
00040 //               done, it creates a DisplayRegion for itself and renders
00041 //               itself in the upper-right-hand corner.
