PinchToZoomScrollable

A widget that makes another one pinch zoom, and return to its initial size and position when released.
PinchToZoomScrollableWidget is based on a fork of InteractiveViewer because the standard widget loses to ScrollView on GestureArena.
Also, the widget can preserve its state by transitioning to the Overlay and back.
