- *
- * #GtkThemingEngine was the object used for rendering themed content

- * loaded as modules.
- *
- * #GtkThemingEngine has been deprecated in GTK+ 3.14 and will be
- * ignored for rendering. The advancements in CSS theming are good
- * enough to allow themers to achieve their goals without the need
- * to modify source code.
