Gtkmm Gtk::Curves forGTK+3

[Christopher Sosa <cristopher7sosa gmail com>]

Hello everyone.

I'm writting an game content editor for my OGRE3D-based game engine 
using C++/Gtkmm (I'm love in GTK+ due their small memory and space 
footprint for my applications). I see an widget called Curves, but was 
deprecated in Gtk 2.4 due are too specialized.

So my question is were can download the updated GTK+3 Curves widget and 
their GTKmm wrapper (specific 3.4.0)? (I will thanks if exists an Glade 
.catalog file).
