Cloned previews get the STF from parent even if that STF is no longer applied

Yeah, I'm on a roll. That's what you get when there are a few hours of dark skies each night and an opportunity to process some new data

- load linear image
- apply STF
- HT
- disable STF
- draw preview (no STF on preview)
- clone preview to image
- new image has STF applied (it should not)

- new image has STF applied (it should not)

Indeed. The current enabled/disabled state of STF is not inherited by newly cloned previews. This little bug is so easy to fix, that it is now fixed

Thanks for the hunt!
