2007-11-02 Michael Natterer <mitch@gimp.org> * app/core/gimpcurve.[ch]: added API to modify free-form curves and properties to listen to curve changes. * app/widgets/gimphistogramview.[ch]: added everything that's needed for rendering a curve with all its color and cursor indicators on top of a histogram. This code will move to a subclass soon. * app/tools/gimpcurvestool.[ch]: removed all curve rendering here. Also removed all explicit updating by connecting to curve signals and updating in the callback. svn path=/trunk/; revision=24045
