+The Porthole widget provides geometry management of a list of arbitrary
+widgets, only one of which may be managed at any particular time.
+The managed child widget is reparented within the porthole and is moved around
+by the application (typically under the control of a Panner widget).

+Layout Semantics

+.LP
+The Porthole widget allows its managed child to request any size
+that is as large
+or larger than the Porthole itself and any location so long as the child
+still obscures all of the Porthole.  This widget typically is used with a
+Panner widget.
