Adds an icon factory to the list of icon factories searched by
gtk_style_lookup_icon_set(). This means that, for example,
gtk_image_new_from_stock() will be able to find icons in factory.
There will normally be an icon factory added for each library or
application that comes with icons. The default icon factories
can be overridden by themes.
