 In addition, I think we need to keep a Rectangle with the bounds
 maintained in each Panel, this would elmininate the constructor call
 to compute intersections on every call.  And since we are likely only
 going to have a handful of panels, this price is worth paying.

+MeasureOrDrawString, and you know why).
