   * work with. The base images and when to use them are described by
   * a Gtk::IconSource.
   * 
   * This function copies @a source , so you can reuse the same source immediately
   * without affecting the icon set.
   * 
   * An example of when you'd use this function: a web browser's "Back
   * to Previous Page" icon might point in a different direction in
   * Hebrew and in English; it might look different when insensitive;
   * and it might change size depending on toolbar mode (small/large
   * icons). So a single icon set would contain all those variants of
   * the icon, and you might add a separate source for each one.
   * 
   * You should nearly always add a "default" icon source with all
   * 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.
   * 
   * gtk_icon_set_new_from_pixbuf() creates a new icon set with a
   * default icon source based on the given pixbuf.
   * @param source A Gtk::IconSource.
