contrast equalizer should be after sigmoid/filmic

else it creates artefacts, this is a display referred tool that works in lab

I personally don't think this is a good idea. Technically there is much more involved. If you really wanna go into this and would want others to test you could see how things could be done in #17780 and #17791 ...

Do I understand this correctly that you agree that the module is in the wrong place but it's complicated to change it?

[jenshannoschwalm]

Nope, not at all i meant it's too complicated - was just hinting there is more involved than the one-liner :-)

Not thinking it's a good idea was about the implications of changing the order. Working in lab space is something completely different than working in "display referred space" as we do after sigmoid or filmic. I am absolutely unsure if we just have different (or even more) artifacts by doing as you propose. So if you provide something just-working i would be willing to test or if you can at least provide samples showing clearly improved results.

contrast equalizer before sigmoid:

contrast eqalizer after sigmoid:

to be honest, it is barely noticeable but in after the effect is stronger, while the haloing is better, in before it's the other way round.
probably it's better visible if I exaggerate the effect.
