439     *
440     * This widgets is intended for large text blocks which are expected to require
441     * the text to be automatically wrapped (i.e. auto inserted line breaks) such
442     * that it would not exceed the label's maximum allowed width according to its
443     * parent container.
444     *
445     * This class overrides get_preferred_height_for_width_vfunc() to fix the
446     * default behaviour of Gtk::Label, which by default calculates a height under
447     * the assumption that EVERY word of the text had a line break, which would
448     * cause the label to claim much more vertical space than actually required for
449     * the text.
