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