Since it looks like you are only concerned with rendering the text, you can
ignore what I had said in the previous email about duplicating the points.
But the strategy I laid out in the previous email still holds. I am pretty
sure there is no functionality for this, so you would have to manually
intercept mouse drag events and change the point location to move the label.
