From Corbin Holtz, "I have completed my mods to the OpenFlight loader (modified files are

attached):
   * Light point strings using the REPLICATE opcode should now be supported
(>=15.6?)

   * Directional lights should now work as in Performer using a viewing
frustrum defined by a direction vector, horizontal angular width, vertical
angular width, and roll angle about the direction vector.  The current
directional light implementation had some bad assumptions which caused
problems with direction vectors not on the XY plane.

   * IVE and OSG reader/writers were updated as appropriate"
