* Android input events include the source from which the input came from.
* We must look at the source of the input event to determine which type
* of jME input it belongs to.
* If the input is from a gamepad or joystick source, the event is sent
* to the JoyInput class to convert the event into jME joystick events.
*
* If the input is from a touchscreen source, the event is sent to the
* TouchProcessor to convert the event into touch events.
* The TouchProcessor also converts the events into Mouse and Key events
* if AppSettings is set to simulate Mouse or Keyboard events.
*
* Android reports the source as a bitmask as shown below.
