Multi-processing and spectral output are supported. |

Wrote rxpiece tool that will render pictures using tiling and |

can handle different output formats and hyperspectral pictures. |

Only runs on a single machine, however -- no NFS locking on |

shared volumes. Mainly a demonstration tool for RpictSimulManager |

C++ class, but may have its uses. |

Fixed a bug in BSDF sampling of sources pointed out by |

David Geisler-Moroder, which tended to overestimate specular |

Added crude ability to read and convert spectra to RGB in ximage, |

ra_bmp, ra_ps, and ra_rgbe programs. Also updated fast tone-mapping |

library to handle spectral HSR inputs at the same time. HSR |

input handling was added in a similar fashion to pcond and pvalue |

Added handling of hyperspectral images to normtiff, a handy program |

results are still reported in RGB. |

Added hyperspectral picture conversion to ra_tiff, with accurate |

color when targeting 16-bit/comp., LogLuv, and float utput, |

Created C++ class for rcontrib and example tool rxcontrib, which |
| 2750 |

is an optional compile in the src/rt directory. The output |
| 2751 |

model is more general in some respects and the operations more |
| 2752 |

efficient, but standard output is not supported, nor is ASCII |
| 2753 |

results data. |
| 2754 |

Added strnstr.c compatibility module in ray/src/common, since |
| 2756 |

it isn't present on Linux derivatives. |

Added WGMDfunc material type with programmable roughness and |

separate modifier paths for the different components. |

Added gensurf -i option at the request of Peter Apian-Bennewitz |
| 2762 |

to reverse surface normals, mostly for data input, when it is |
| 2763 |

a bit more difficult to adjust. |

Added rad -N option to rholo call for multiprocessing when |

mkillum and/or mkpmap are involved in octree prep. |
