Fixed bug where mesh instances were not being freed, so subsequent calls |

It's a nasty format in so many ways -- I don't yet support conversion |

It's the most horrible image format I've ever seen, and I've seen a lot. |

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

If that isn't enough, then there's probably no hope, anyway. |

Added tone-mapping and monitor primary options to ra_bmp. This gives |
