+// Group that adds scrollbars so you can scroll around the area
+// covered by all the child widgets. For most uses you will make
+// a single child widget, this child may resize in it's layout()
+// and the scrollbars will adjust to match.
+//
+// Due to clipping problems no subclasses of Window may be used
+// as child widgets.
