* Fixed artifacts thanks to Alberto * Added blur to Color propagation * Clean format code - small improvments * color propagation: Enable old mode at blur = 0 * Improve GUI * color propagation: smooth progress bar for blur > 0 * change label * Some cleanups * color propagation: small speedup for blur > 0 * color propagation: speedup for blur > 0 when region with clipped highlights is small * Speed-up for blur=1 - clean GUI code * color propagation: cleanups * Harmonize events in tonecurve.cc * tonecurve.cc : cleanup * Highlight reconstruction: small changes to gui * Use Gtk::Box instead of Gtk::VBox * Change maximum number of blur levels to 4 * Suppress BENCHFUN * Suppress bad commit locallabtools Co-authored-by: Desmis <jdesmis@gmail.com> Co-authored-by: Ingo Weyrich <heckflosse67@gmx.de>
