French RawTherapee version

Hey

I am not finished updating that article, so hold on with translating for a few days. Once done with it, there will still be duplication to be removed from Exposure - RawPedia

FYI, we used various terms for the spots you put in a curve, and I am working on consistently calling them “control points” (that is the proper term). Also the “pipette” and all other ways we refer to it will be consistently called a “color picker”.

Regards
