/**
 * GtkHeaderBar is similar to a horizontal #GtkBox. It allows children to
 * be placed at the start or the end. In addition, it allows a title and
 * subtitle to be displayed. The title will be centered with respect to
 * the width of the box, even if the children at either side take up
 * different amounts of space. The height of the titlebar will be
 * set to provide sufficient space for the subtitle, even if none is
 * currently set. If a subtitle is not needed, the space reservation
 * can be turned off with gtk_header_bar_set_has_subtitle().
 * 
 * GtkHeaderBar can add typical window frame controls, such as minimize,
 * maximize and close buttons, or the window icon.
 * 
 * For these reasons, GtkHeaderBar is the natural choice for use as the custom
 * titlebar widget of a #GtkWindow (see gtk_window_set_titlebar()), as it gives
 * features typical of titlebars while allowing the addition of child widgets.
