manage a collection of floating widgets

 This container widget maintains a collection of floating widgets that can be
 displayed over the top of a single base widget. The box itself is entirely
 occupied by the base widget, and by default when no floats are created or
 displayed it will behave essentially invisibly, as though the box were not
 there and the base widget was an immediate child of the container the
 floatbox is inside.
