+Add the given geometry file to the list of geometry to render for
+intermediate views if direct geometry rendering is available.  The
+second argument gives the name(s) of any portal geometry files
+associated with this section.  Multiple portal file names are separated
+by spaces.  A single octree file will be given for the geometry, ending
+in the ".oct" suffix.  Portal files will be given as zero or more
+Radiance scene description file names.  If no portals are given for
+this section, the string may be NULL.  The character strings are
+guaranteed to be static (or permanently allocated) such that they may
+be safely stored as a pointer.  The same pointers or file lists may be
+(and often are) given repeatedly.  If a given geometry file does not
+exist, the call should be silently ignored.  If gf is NULL, then the
+last section has been given, and the display can be updated with the
+new information.
