A #GtkSeparatorToolItem is a #GtkToolItem that separates groups of other
#GtkToolItems. Depending on the theme, a #GtkSeparatorToolItem will
often look like a vertical line on horizontally docked toolbars.
If the #GtkToolbar child property “expand” is true and the property
#GtkSeparatorToolItem:draw is false, a #GtkSeparatorToolItem will act as
a “spring” that forces other items to the ends of the toolbar.
