 * Icons in an icon factory are named by a stock ID, which is a simple string identifying the icon. Each GtkStyle has a list of GtkIconFactory derived from the current theme; those icon factories are consulted first when searching for an icon. If the theme doesn't set a particular icon, GTK+ looks for the icon in a list of default icon factories, maintained by gtk_icon_factory_add_default() and gtk_icon_factory_remove_default(). Applications with icons should add a default icon factory with their icons, which will allow themes to override the icons for the application.

   * fields wildcarded, which will be used as a fallback if no more
   * specific source matches. Gtk::IconSet always prefers more specific
   * icon sources to more generic icon sources. The order in which you
   * add the sources to the icon set does not matter.
