 * implementations.

 * Before style properties can be stored in GtkStyleProperties, they
 * must be registered with gtk_style_properties_register_property().
 * 
 * Unless you are writing a #GtkStyleProvider implementation, you
 * are unlikely to use this API directly, as gtk_style_context_get()
 * and its variants are the preferred way to access styling information
 * from widget implementations and theming engine implementations
 * should use the APIs provided by #GtkThemingEngine instead.
