onGetEpicenter
Rect onGetEpicenter (Transition transition)
Implementers must override to return the epicenter of the Transition in screen
coordinates. Transitions like Explode depend upon
an epicenter for the Transition. In Explode, Views move toward or away from the
center of the epicenter Rect along the vector between the epicenter and the center
of the View appearing and disappearing. Some Transitions, such as
Fade pay no attention to the epicenter.
| Parameters |

Transition:
The transition for which the epicenter applies. |
| Returns |

Rect |
The Rect region of the epicenter of transition or null if
there is no epicenter.
