            	pass it into the Activity after initial creation. The
            	same applies to the actual shape the animation must
            	run for, since e.g. subsetted shapes are generated
            	close before the animation starts, too (this is not
            	necessary in and out of itself, but for performance
            	reasons. Otherwise, character iterations produce tons
            	of subset shapes).

                Shape to play the animation on.

                Attribute layer to change the animated values on.
