- Ensure _isInteractive is set to NO immediately after it is used in
  animateOperation:

- Ensure the percent driven methods are triggered when the interaction
  is actually interactive.

Added more specs covering viewControllerForKey:
Fixed View Size at start of zoom transition

View would have the wrong height at the begining of the transition then
it would snap to the correct height. This fixed it for me.
frames should return CGRectZero for views that are not on screen

- Breaking change for custom transitions: You must now detect for
  CGRectZero from an initial frame, since the view is not on screen its
  frame is not known.
