[Bf-committers] Luminance patches

[Thomas Beck]

Hi Antony,

I'm for "fix it properly by breaking old files slightly". I (the artists
around me agree) prefer to let old files break (in terms of color
correction) when we get a working color pipeline with correct formulas in
exchange for it. I would really not like to see a wrong behavior carried on
endless times just to be compatible to infinity and beyond ;) .

Greetings, Thomas
