	 * 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. #GtkIconSet 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.
