Internal processing in 32 bit depth?

[shijan]

Here it is: 8 bit only filters list
(tested with Hybrid UI on macOS 10.14.6):
DeGrain -> MLDegrain
DeGrain -> TemporalDegrain
Artefacts -> DeCrawl -> DotKill
Artefacts -> DeCrawl -> DeDot
Artefacts -> DeRainbow -> BiFrost
Artefacts -> DeRainbow -> SSIQ
Artefacts -> DeCross
Line -> AntiAliasing -> SangNomMod (removed from Hybrid due conflict with SangNom)
Line -> Resizer -> Anime4KCPP

Overall situation is not so bad...
