I had another related fix for referencePlayfield that I added to this.

from preamble:

"Change Set:		EtoyReferencePlayfieldFix-kfr
Date:			8 September 2003
Author:			Karl Ramberg

Fix to return the first owning playfield so we get correct x and y
values for embedded morphs.

Ned Konz simplified the code and added a fix for a bug caused by having
a viewer open on a playfield.
