Add a threshold before dragging begins

[mkdynamic]

Is there a way to enforce a minimum distance threshold when you pointerdown before the drag begins?

My elements are also clickable, and a side-effect of them being draggable is that if you are not super precise with your pointer down (absolutely still, don't move even 1 pixel), the click is essentially ignored, because the drag takes over. But you didn't actually want to drag in this case, and nothing moves.
