- library data allows pointcache writing (hard to know how this should work long term so ifdef'd for now) - changing the frame now updates the dupligroup objects - BKE_ptcache_ids_from_object(), option to get the id's from duplis note! scene_update_tagged() is called from the main() loop, and runs BKE_ptcache_quick_cache_all(), this could become a performance issue, especially with duplis, should probably not call BKE_ptcache_quick_cache_all() all the time, even when not playing back animation.
