Added ability of mgf2rad to convert spectral data at least |

for light, glow, plastic, and metal primitive types. Need |

Minor change to rcollate to allow explicit byte records to |
| 2682 |

be any specified length without checks against header input. |

Added rxpict rendering tool based on C++ RpictSimulManager class. |
| 2717 |

Multi-processing and spectral output are supported. |

Wrote rxpiece tool that will render pictures using tiling and |
| 2720 |

can handle different output formats and hyperspectral pictures. |
| 2721 |

Only runs on a single machine, however -- no NFS locking on |
| 2722 |

shared volumes. Mainly a demonstration tool for RpictSimulManager |
| 2723 |

C++ class, but later added to standard Rmakefile targets. |

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

David Geisler-Moroder, which tended to overestimate specular |

contributions for some BSDFs. |

Added ability of gendaymtx to read EPW as well as WEA files. |

When EPW input is provided, the 3-hour average dew point is |

Removed limitation in rfluxmtx, which was disallowing distant |

spectral input pictures. It also adds a -N option for multi- |

Changed default matrix representation to float rather than |

double, which uses less RAM and supports faster operations |

Fixed slight bias in indirect calculation caused by ambient |

Altered rvu "origin" command to take shift amounts forward, |
