Constructs a pan gesture recognizer.
@alias PanRecognizer
@constructor
@augments GestureRecognizer
@classdesc A concrete gesture recognizer subclass that looks for touch panning gestures.
@param {EventTarget} target The document element this gesture recognizer observes for mouse and touch events.
@param {Function} callback An optional function to call when this gesture is recognized. If non-null, the
function is called when this gesture is recognized, and is passed a single argument: this gesture recognizer,
e.g., <code>gestureCallback(recognizer)</code>.
@throws {ArgumentError} If the specified target is null or undefined.
Constructs a pan gesture recognizer .
