/**
 * GtkSymbolicColor is a boxed type that represents a symbolic color.
 * It is the result of parsing a
 * [color expression][gtkcssprovider-symbolic-colors].
 * To obtain the color represented by a GtkSymbolicColor, it has to
 * be resolved with gtk_symbolic_color_resolve(), which replaces all
 * symbolic color references by the colors they refer to (in a given
 * context) and evaluates mix, shade and other expressions, resulting
 * in a #GdkRGBA value.
 * 
 * It is not normally necessary to deal directly with #GtkSymbolicColors,
 * since they are mostly used behind the scenes by #GtkStyleContext and
 * #GtkCssProvider.
 * 
 * #GtkSymbolicColor is deprecated. Symbolic colors are considered an
 * implementation detail of GTK+.
