Subject: Color management: change reference space from Linear ACES to Linear.
 This will have no effect on the end result, because it is only an
 intermediate space and scene_linear was already set to Linear. It does avoid
 some unnecessary matrix transforms which should be a bit faster, and it makes
 it more clear what's happening.
