* originator - saves cpu time if you know the inserted object |

* INS_ON_TOP: Always put object on top. Generally only needed when loading |

* files from disk and ordering needs to be preserved. |
| 378 |
* INS_BELOW_ORIGINATOR: Insert new object immediately below originator - |
| 379 |

* beneath the player, but not actually above it. Note - the |

* map and x,y coordinates for the object to be inserted must |
| 382 |
* match the originator. |
| 383 |
* INS_MAP_LOAD: disable lots of checkings done at insertion to |
