314 * Most are fairly explanatory:
315 * INS_NO_MERGE: don't try to merge inserted object with ones alrady
316 * on space.
317 * INS_ABOVE_FLOOR_ONLY: Put object immediatly above the floor.
318 * INS_NO_WALK_ON: Don't call check_walk_on against the
319 * originator - saves cpu time if you know the inserted object
320 * is not meaningful in terms of having an effect.
321 * INS_ON_TOP: Always put object on top. Generally only needed when loading
322 * files from disk and ordering needs to be preserved.
323 * INS_BELOW_ORIGINATOR: Insert new object immediately below originator -
324 * Use for treasure chests so the new object is the highest thing
325 * beneath the player, but not actually above it. Note - the
326 * map and x,y coordinates for the object to be inserted must
327 * match the originator.
328 * INS_MAP_LOAD: disable lots of checkings done at insertion to
329 * speed up map loading process, as we assume the ordering in
330 * loaded map is correct.
331 *
332 * Note that INS_BELOW_ORIGINATOR, INS_ON_TOP, INS_ABOVE_FLOOR_ONLY
333 * are mutually exclusive. The behaviour for passing more than one
334 * should be considered undefined - while you may notice what happens
335 * right now if you pass more than one, that could very well change
336 * in future revisions of the code.
