@short A widget containing other widgets which can be paned.
With this widget you can create larger scrollable areas. This could be one larger
client-widget or any number of widgets "spanning" the scrollable area. This
widget doesn't provide scrollbars you can only move to a position by using the
PG_ScrollArea::ScrollTo method.
