// GtkViewsFixed is a subclass of GtkFixed that can give child widgets
// a set size rather than their requisitioned size (which is actually
// a minimum size, and that can cause issues). This behavior is
// controlled by gtk_views_fixed_set_widget_size; the default is to
// use the Widget's requisitioned size.
