code: function phantomTouchMove(e) {
      if (e.synthetic) return;
  
      e.preventDefault();
      e.stopPropagation();
  
      moveFingers(e);
  
      if (mouseIsDown) {
        fireTouchEvents('touchmove', e);
      }
    }
docs: Prevent all mousemove events from firing. We'll fire one (and only one) manually at touchend.
