--  <description>
--  Marks are positions in a buffer which move when the buffer is modified,
--  so that they always point to the same place in the buffer.
--  They are automatically destroyed when the buffer is destroyed, unless
--  you have explicitly call Ref on the mark.
--  See Gtk.Text_Buffer for various functions dealing with marks. In
--  particular, Gtk.Text_Buffer.Get_Buffer can be used to retrieve the
--  buffer from a mark.
