An extendible class that allows a developer to handle Altus gestures (such as panning and zooming) in a unique way. There is also an existing sub-class, ClassicGestureReceiver, that handles gestures in the classic Altus 2.0 way. Gesture events are generated by Altus from the raw stream of finger/pointer events. If you would like access to the raw stream of finger/pointer events without Altus gesture generation, please see RawInputHandler. More...
