-// with the presented view occupying a rectangle supplied by the delegate, or
-// defaulting to a square in the center of the presenter's view. The
-// presentation animation will change the size of the rectangle to match the
-// final presented size. For dismissal, the same animation is done in reverse.

-// conforms to ZoomTransitionDelegate, then the receiver's delegate will be
-// nil. If multiple objects in |possibleDelegates| conforms to the protocol,
-// then the first one will become the receiver's delegate.
