Documentation

A visitor for traversing a scene graph establishing the OpenGL visuals are required to support rendering of that scene graph. The results can then be used by applications to set up there windows with the correct visuals. Have a look at src/osgGLUT/Viewer.cpp's Viewer::open() method for an example how to use it.
