with big enough hammer ...

I wonder if limitation more about displaying results here relative to
processing algo? We can make histogram 2x longer, but what if generated
result STILL out of new range? I wonder how other software solves it ....


Meanwhile, ffmpeg git gained color management support, but I am not sure
how useful it might be for us:


https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/dddf536d3d575a8f7cf7eb85bdd2b2d20fc36369


and related commits.

Problem is - I tried to ignite some interest in cingg but may be I am wrong
person to do that, or developers want different codebase (more modern c++,
etc).

But we do not have thousands of users who can somewhat cooperate and buy
year or so of professional developer time (HaikuOS gains like $50k in
donations yearly, but they whole OS .. without /proc fs curiously ....).

So we stick in circle where devs consider our program  irrelevant/too
complex/too alien and users lack feature/bug resolution so they just
install whatever others install - DVR, blender .....

In some sense I think we are much more OG opensource/libre/community
software, not piggybacking on big corporate codedrop/development, but few
cares about that ...
