If your GnomeUIInfo entries use GNOME_APP_PIXMAP_DATA or
GNOME_APP_PIXMAP_FILENAME for pixmaps, you have to create a
<link linkend="GtkIconFactory">GtkIconFactory</link>, add it
to the list of default factories, then create a
<link linkend="GtkIconSet">GtkIconSet</link> for each of your
own icons. Add the sets to the factory, and use the id in the
<link linkend="GtkActionEntry">GtkActionEntry</link> like a
regular GTK+ stock id.
