Hi,

the gamma module does not do what it says anymore. It's a leftover of dt
0.x before the output colour profile was added.

It has always been there but didn't appear in the history before. It
still doesn't appear in UI. I don't remember why we made every module
appear in the history now (except the mask manager, which function I
don't understand), but here it is.

The gamma module is now only converting the floating point output of the
pipe (image or masks) to 8 bits unsigned integers, to be sent to the
display. As such, it is not used when exporting to a file.

Aurélien.
