| * #GThemedIcon is an implementation of #GIcon that supports icon themes. |
| * #GThemedIcon contains a list of all of the icons present in an icon |
| * theme, so that icons can be looked up quickly. #GThemedIcon does |
| * not provide actual pixmaps for icons, just the icon names. |
| * Ideally something like gtk_icon_theme_choose_icon() should be used to |
| * resolve the list of names so that fallback icons work nicely with |
| * themes that inherit other themes. |
