/* Header Bar
*
* GtkHeaderBar is a container that is suitable for implementing
* window titlebars. One of its features is that it can position
* a title (and optional subtitle) centered with regard to the
* full width, regardless of variable-width content at the left
* or right.
*
* It is commonly used with gtk_window_set_titlebar()
