Will make it so the NPC will always display while loaded(in nearby levels). For example, with exceptionally large NPC's, on gmaps while walking it will suddenly 'pop' into view.

This will make it so scripters can give priority to larger NPCs so players don't get that unfortunate effect. However, it will not try to display levels not loaded as per gmap standard.

I don't really think this is the best way to add this kind of thing, but I can't think of a better way right now.
