--  <description>
--  Gtk_Arrow should be used to draw simple arrows that need to point in one
--  of the four cardinal directions (up, down, left, or right). The style of
--  the arrow can be one of shadow in, shadow out, etched in, or etched out.
--  Note that these directions and style types may be ammended in versions of
--  Gtk to come.
--
--  Gtk_Arrow will fill any space alloted to it, but since it is inherited
--  from Gtk_Misc, it can be padded and/or aligned, to fill exactly the space
--  you desire.
--
--  Arrows are created with a call to Gtk_New. The direction or style of an
--  arrow can be changed after creation by using Set.
