Added support in normtiff for floating-point and 16-bit/sample TIFF input |

Changed marksources() routine (src/rt/source.c) to check all |

Added a source occluder cache to accelerate shadow testing. This |

rpict options on the command line, and puts everything into the right |

Increased -aa default value for all renderers (and also -ad and -as in |

Fixed problems with effective ray lengths computed for dielectric |
