Single clicking a point will make the point follow the mouse

[basvangeffen]

The latest commit caused this issue: a single click on a point will result in that point following the mouse (as if dragging). The problem seems to be caused by the "Reset" line in the drop function.

dragPoint = dragX = dragY = undefined; is only executed if "newPos" is truthy, which it is not if you click a point (with default dragSensitivity).

Thanks! It should work now. It resets if the newPos is falsy, otherwise if the drop is not cancelled. That leaves the opportunity to cancel the drop.
