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"
