****** COMPATIBILITY CHANGE ******** | 
| 1919 |

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. | 
| 1924 |

 | 
| 1925 | 
+ | 
Changed dctimestep so that output matrices (-n > 1) are preceded by a | 
| 1926 | 
+ | 
header, and added support for float and double output formats with -o[fd]. | 
| 1927 | 
+ | 
 |

Introduced eplus_adduvf program to compute user view factors for EnergyPlus. | 
| 1929 |

 | 
| 1930 | 
+ | 
Changed image-plane sampling in rpict to use Hilbert curve, which gives | 
| 1931 | 
+ | 
less of a brushed/striped appearance to output pixels with -u- (default). |
