Currently we use a _scriptTransformed flag for these cases.
Once a character has been transformed by actionscript we won't
allow PlaceObject2 to modify it's matrix again.

The get_accept_anim_move() is the function being called to know
wheter PlaceObject2 movement are allowed. It currently checks
*not* the _scriptTransformed and the _dynamicallyCreated flag.

If what Zou is saying in IRC is correct it should only use _scriptTransformed

12:21 < zou> PLACE and REPLACE need to support an ID for the new character, 
PLACE, MOVE, REPLACE all use dpeth to refer the old character.
12:22 < strk> Ok, so my question above was: will MOVE or REPLACE tags be 
effective no matter what kind of instance is found at the specified depth of 
the old
              character ?
12:25 < zou> yes, I think so. no matter what occupies the specified depth.
