Improved rendering speed of scenes with aliases by not entering new | 
| 1909 | 
  | 
modifiers into table if they are the same as the previously defined | 
| 1910 | 
  | 
modifier for that name. |

Made it so icalc and rcalc search RAYPATH directories for *.cal files | 
| 1913 | 
+ | 
given on command line.  This simplifies script writing and makes these | 
| 1914 | 
+ | 
utilities consistent with other tools in Radiance. |

Added triangulation routine to handle convex polygons in obj2mesh. |

****** COMPATIBILITY CHANGE ******** |

Made backface visibility apply to all material types, including | 
| 1920 | 
+ | 
transparent and translucent materials (except dielectric and interface). | 
| 1921 | 
+ | 
This makes the option useful in cases where adjacent trans surfaces | 
| 1922 | 
+ | 
are placed next to each other by a modeler that only understands | 
| 1923 | 
+ | 
volumetric objects. |
