Fixed behavior of source primitive using illum with no alternate |

Changed ambient calculation so that -ad will not limit recursion |

depth, and a minimum of 27 samples will be sent out for each stored |

ambient value, or 3 samples if -aa is 0 (caching off). |

Rearranged the way ray contributions are computed so that it might be |
| 1427 |

possible to use rtrace to derive daylight coefficients and optical |

contribution weights for each ray, which combined with the -ti (or -tI) |
| 1430 |

option permits the contribution of selected surfaces or sources to |
| 1431 |

be determined. Using the -oTW option, one should also specify |
| 1432 |

options "-dt 0 -aa 0 -as 0" for optimal results. In particular, |

one cannot expect reasonable tallies with -ab >= 1 and irradiance |

caching on (-aa > 0). |

The same code modifications included a change to the indirect computation |
| 1437 |

with caching switched off (-aa 0). Whereas before, the number of secondary |

Added tilde ('~') output option as part of the -o* specification of |

Switched default options in rtrace to use Russian roulette. (Rpict and rvu |
