public PopupWindowPlacerBuilder leastOverlapCorner() {
		add(new LeastOverlapCornerPopupWindowPlacer());
		return this;
	}
Set the next PopupWindowPlacer to be one that tries to make the placement that is
allowed to overlap the inner bounds, but with the least overlap area.  Tie-breaker
order is first in this order: Bottom Right, Bottom Left, Top Right, Top  Left.
<p>
Should never return null, except if using impractical parameters, such as using
outer bounds that are smaller than inner bounds.
