31.     --  The Gtk_Gamma_Curve widget is a child of Gtk_Curve specifically for editing

32.     --  gamma curves, which are used in graphics applications such as the Gimp.

33.     --

34.     --  The Gamma_Curve widget shows a curve which the user can edit with the mouse

35.     --  just like a Gtk_Curve widget. On the right of the curve it also displays 5

36.     --  buttons, 3 of which change between the 3 curve modes (spline, linear and

37.     --  free), and the other 2 set the curve to a particular gamma value, or reset

38.     --  it to a straight line.
