 *    on space.
 * INS_ABOVE_FLOOR_ONLY: Put object immediatly above the floor.
 * INS_NO_WALK_ON: Don't call check_walk_on against the
 *    originator - saves cpu time if you know the inserted object
 *    is not meaningful in terms of having an effect.
 * INS_ON_TOP: Always put object on top.  Generally only needed when loading
 *     files from disk and ordering needs to be preserved. 
 * INS_BELOW_ORIGINATOR: Insert new object immediately below originator -
 *     Use for treasure chests so the new object is the highest thing
 *     beneath the player, but not actually above it.  Note - the
 *     map and x,y coordinates for the object to be inserted must
 *     match the originator.
 * INS_MAP_LOAD: disable lots of checkings done at insertion to
 *     speed up map loading process, as we assume the ordering in
 *     loaded map is correct.
 *
 * Note that INS_BELOW_ORIGINATOR, INS_ON_TOP, INS_ABOVE_FLOOR_ONLY
 * are mutually exclusive.  The behaviour for passing more than one
 * should be considered undefined - while you may notice what happens
 * right now if you pass more than one, that could very well change

330			* INS_BELOW_ORIGINATOR: Insert new object immediately below originator -
