31 * This is a special TextNode that automatically updates itself with output
32 * from a SceneGraphAnalyzer instance. It can be placed anywhere in the world
33 * where you'd like to see the output from SceneGraphAnalyzer.
34 *
35 * It also has a special mode in which it may be attached directly to a
36 * channel or window. If this is done, it creates a DisplayRegion for itself
37 * and renders itself in the upper-right-hand corner.
