// 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.
