Interface definition for a callback to be invoked when a touch event is dispatched to a scene.
The callback will be invoked before the Scene.OnTouchListener
is invoked. This is invoked
even if the gesture was consumed, making it possible to observe all motion events dispatched to
the scene.

onPeekTouch
( HitTestResult
hitTestResult, MotionEvent
motionEvent)
Called when a touch event is dispatched to a scene. The callback will be invoked before the Scene.OnTouchListener
is invoked. This is invoked even if the gesture was consumed, making
it possible to observe all motion events dispatched to the scene. This is called even if the
touch is not over a node, in which case getNode()
will be null.
