Currently the feature available in transit to reverse play a transition is
auto-reverse which will play a transition in reverse mode once a transition
is complete. This feature helps the user to revert a transition at any point
of time when transition is going on.
New API added.
While doing pinch zoom, we will be doing zoom transit effect from one step to other, during that transit if user do the pinch in reverse direction this API can be called so that transition will be reverted easily.
