The top_window_group is used for windows like popup menus, which should appear above shell chrome like the panel. Since we want important actors such as the screen keyboard or modal dialogs to be shown above those windows, add their actors after adding global.top_window_group to this.uiGroup and provide a new function addTopChrome() to add important chrome above the top_window_group.
