Bug 676 - Add support for native Mouse Pointer rendering (Rasp.-Pi.)

- Utilizing layer element 2000 for PointerIcon

- Using NEWT PointerIcon code

- Using MouseListener to update PointerIcon position
  - FIXME: Check whether we shall intercept sendMouseEvent directly (lag)

Misc:
  - Properly open, assign and close the BCM display handle
  - Properly destroy the window (BCM element)
  - Prepare for multiple windows, set position and size
