Feature suggestion: handle drag event

[appeltonen]

Off-click fires when touch device user ends target element drag. I suggest you add a touchmove event handler
document.addEventListener("touchmove", touchMoveHandler, true);
and variable
var touchDrag = false;

Then add

function touchMoveHandler(event) {
  touchDrag = true;
}

And at the beginning of offClickEventHandler

if( touchDrag ) {
  touchDrag = false;
  return;
}

This would prevent off-click from firing when user was dragging target element.

That makes sense. Since this is "off-click" and we could go as far as touch == click. But dragging != click and should not trigger off-click.
