/* These are flags passed to insert_ob_in_map and |

* insert_ob_in_ob. Note that all flags may not be meaningful |
| 461 |
* for both functions. |
| 462 |
* Most are fairly explanatory: |
| 463 |
* INS_NO_MERGE: don't try to merge inserted object with ones alrady |
| 464 |
* on space. |
| 465 |
* INS_ABOVE_FLOOR_ONLY: Put object immediatly above the floor. |
| 466 |
* INS_NO_WALK_ON: Don't call check_walk_on against the |
| 467 |
* originator - saves cpu time if you know the inserted object |
| 468 |
* is not meaningful in terms of having an effect. |
| 469 |
* INS_ON_TOP: Always put object on top. Generally only needed when loading |
| 470 |
* files from disk and ordering needs to be preserved. |
| 471 |
* INS_BELOW_ORIGINATOR: Insert new object immediately below originator - |
| 472 |
* Use for treasure chests so the new object is the highest thing |
| 473 |
* beneath the player, but not actually above it. Note - the |
| 474 |
* map and x,y coordinates for the object to be inserted must |
| 475 |
* match the originator. |
| 476 |
* INS_MAP_LOAD: disable lots of checkings done at insertion to |
| 477 |
* speed up map loading process, as we assume the ordering in |
| 478 |
* loaded map is correct. |
| 479 |
* |
| 480 |
* Note that INS_BELOW_ORIGINATOR, INS_ON_TOP, INS_ABOVE_FLOOR_ONLY |
| 481 |
* are mutually exclusive. The behaviour for passing more than one |
| 482 |
* should be considered undefined - while you may notice what happens |
| 483 |
* right now if you pass more than one, that could very well change |
| 484 |
* in future revisions of the code. |
