  42                 Since attribute layers can only be generated when the
  43                 animation starts, the Activity owner must be able to
  44                 pass it into the Activity after initial creation. The
  45                 same applies to the actual shape the animation must
  46                 run for, since e.g. subsetted shapes are generated
  47                 close before the animation starts, too (this is not
  48                 necessary in and out of itself, but for performance
  49                 reasons. Otherwise, character iterations produce tons
  50                 of subset shapes).
