--  <description>
--  Gtk.Hsv.Gtk_Hsv is the "color wheel" part of a complete color selector
--  widget. It allows to select a color by determining its HSV components in an
--  intuitive way. Moving the selection around the outer ring changes the hue,
--  and moving the selection point inside the inner triangle changes value and
--  saturation.
--
--  Gtk.Hsv.Gtk_Hsv has been deprecated together with
--  Gtk.Color_Selection.Gtk_Color_Selection, where it was used.
