Detailed Description
A PinchGesture is emitted when the user moves two fingers towards or away from each other.
This gesture can be in one of three states; when the pinch gesture is first detected, its state is set to Gesture::Started. After this, if there is change in the gesture, the state will be Gesture::Continuing. Finally, when the gesture ends, the state of the gesture changes to Gesture::Finished.
A pinch gesture will continue to be sent to the actor under the center point of the pinch until the pinch ends.

The scale factor from the start of the pinch gesture till the latest pinch gesture.

The speed at which the user is moving their fingers.
