+ * @Title: GtkThemingEngine
+ * @See_also: #GtkStyleContext
+ *
+ * #GtkThemingEngine is the object used for rendering themed content
+ * in GTK+ widgets. Even though GTK+ has a default implementation,
+ * it can be overridden in CSS files by enforcing a #GtkThemingEngine
+ * object to be loaded as a module.
+ *
+ * In order to implement a theming engine, a #GtkThemingEngine subclass
+ * must be created, alongside the CSS file that will reference it, the
+ * theming engine would be created as an .so library, and installed in
+ * $(gtk-modules-dir)/theming-engines/.
+ *
+ * #GtkThemingEngine<!-- -->s have limited access to the object they are
+ * rendering, the #GtkThemingEngine API has read-only accessors to the
+ * style information contained in the rendered object's #GtkStyleContext.
