The gamma curve widget
======================

Description
-----------

   Lets the user edit a gamma curve (a one-to-one mapping usually used
to adjust the intensity of an image to the physical characteristics of
the output device).  You can set the minimum and maximum values for
input and output.  You can set the initial vector as well.  You are
guaranteed that every input value will have a (not necessarily unique)
output value specified.  Derived from Note: GtkVBox.  Makes use of
Note: GtkCurve to draw the curve.
