* This set of controls performs orbiting, dollying (zooming), and panning.
* Unlike TrackballControls, it maintains the "up" direction object.up (+Y by default).
*    Orbit - left mouse / touch: one finger move
*    Zoom - middle mouse, or mousewheel / touch: two finger spread or squish
*    Pan - right mouse, or arrow keys / touch: three finger swipe
