https://github.com/archont00/cinepaint-oyranos I was reading oyranos website and especially archive.org version of this site, and found out this specific tool was used back in 2011 for showcasing image editing on wide-gamut monitors. There apparently is draft X color management spec, implemented by basically CompICC as server side and icc-examin / sample image viewer /cinepaint as clients. There even was Suse-based live cd from 2011, but it obviously will not fly (with hw 3d accel) on more modern GPUs ..:( http://www.oyranos.org/compicc/index.html http://www.oyranos.org/libxcm/index.html "The X Color Management specification allows to attach colour regions to X windows to communicate with colour servers." So, it was/is region-based, not per-window (makes sense due to in-window controls, for example) https://web.archive.org/web/20111116054348/http://www.oyranos.org/page/2/ " CinePaint full screen Posted on September 8, 2011 On my git repository with CinePaint patches is the full screen mode changed. It uses the GTK funtionality. That mode is now window manager based and will not work with twm. The old code is still ifdefed for users who rely on that and compile it. Putting a full fledged solution like in gqview inside CinePaint would have been too much work. New is as well resizing of frames in the flip book, to allow me to load a bunch of cameraRAW images and watch them much like in a slide show. Colour regions are updated for the colour server. And last but not least a fix in now available, to let CinePaint run on non KWin and non Compiz window managers. I tested on twm. The package is patched in OBS.

Anyone brave enough for compiling from git? :) I have it compiled on Slackware 15.0 i586, so it ought to be compileable on ~modern Linux.
