--  <description>
--  Gtk_Cell_Renderer_Spin renders text in a cell like Gtk_Cell_Renderer_Text
--  from which it is derived. But while Gtk_Cell_Renderer_Text offers a simple
--  entry to edit the text, Gtk_Cell_Renderer_Spin offers a Gtk_Spin_Button
--  widget. Of course, that means that the text has to be parseable as a
--  floating point number.
--
--  The range of the spinbutton is taken from the adjustment property of the
--  cell renderer, which can be set explicitly or mapped to a column in the
--  tree model, like all properties of cell renders. Gtk_Cell_Renderer_Spin
--  also has properties for the climb rate and the number of digits to display.
--  Other Gtk_Spin_Button properties can be set in a handler for the
--  start-editing signal.
--
--  The Gtk_Cell_Renderer_Spin cell renderer was added in GTK+ 2.10.
