/*
 * NOTES:
 * 1. The IFSG wrapper classes shall be aimed at creating a VRML-like
 *    intermediate scenegraph representation. Although objects are
 *    readily created and added to the structure, no provision shall
 *    be made to inspect the structures in detail. For example the
 *    SCENEGRAPH class may contain various SGSHAPE and SCENEGRAPH
 *    nodes but there shall be no provision to extract those nodes.
 *    This was done because in principle all the detailed data shall
 *    only be handled within the SG* classes and only data processed
 *    via GetRenderData() shall be available via the wrappers.
