Bad news about piecewise curves in the Print plugin

Unfortunately, the gtkcurve widget doesn't allow setting the control points of the curve, only setting a dense curve (gtk_curve_set_vector). There may be a back door way of doing it, but that carries obvious hazards.

There's also no official interface for extracting the control points.

The upshot may wind up being that we supply only the dense curve interface to the GIMP plugin. That would be unfortunate.

The GtkCurve widget is basically deprecated and scheduled for removal from GTK+. I would suggest that if you need such a widget you simply copy the code and change the namespace. You can then add the API you need.

That's good to know. Thanks.
