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. As of GTK+ 2.20, GtkGammaCurve has been deprecated since it is too specialized.gtkGammaCurve is the equivalent of gtkGammaCurveNew.
