     *PLEASE NOTE:*  This widget is considered too
     specialized/little-used for GTK+, and will in the future be moved
     to some other package.  If your application needs this widget,
     feel free to use it, as the widget does work and is useful in some
     applications; it's just not of general interest. However, we are
     not accepting new features for the widget, and it will eventually
     move out of the GTK+ distribution.   The 'GtkGammaCurve' widget is
     a variant of 'GtkCurve' specifically for editing gamma curves,
     which are used in graphics applications such as the Gimp.

     The 'GtkGammaCurve' widget shows a curve which the user can edit
     with the  mouse just like a 'GtkCurve' widget. On the right of the
     curve it also displays 5 buttons, 3 of which change between the 3
     curve modes (spline, linear and free), and the other 2 set the
     curve to a particular gamma value, or reset it to a straight line.
