// 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 finter swipe

/**
 * @param localElement - Control events (like mousedown) are started only if mouse is inside
 * 		localElement, but can extend into domElement (mousemove), useful for small or multiple
