 *
 * #StThemeContext is responsible for managing information global to a tree of styled objects,
 * such as the set of stylesheets or the default font. In normal usage, a #StThemeContext
 * is bound to a #ClutterStage; a singleton #StThemeContext can be obtained for a #ClutterStage
 * by using st_theme_context_get_for_stage().
