= 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()
