    <summary>The <see cref="T:Gtk.Curve" /> widget allows the user to edit a curve covering a range of values.</summary>
    <remarks>
      <para>
      The <see cref="T:Gtk.Curve" /> widget allows the user to edit a curve covering a range of values. It is typically used to fine-tune color balances in graphics applications like the Gimp. The <see cref="T:Gtk.Curve" /> widget has 3 modes of operation - spline, linear and free. In spline mode the user places points on the curve which are automatically connected together into a smooth curve. In linear mode the user places points on the curve which are connected by straight lines. In free mode the user can draw the points of the curve freely, and they are not connected at all.

      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. (FIXME: will it remain in GTK#?)
