fmtconv/Avisynth+: resize, bitdepth and colorspace conversions

[StvG]

I guess there will be some additional filtering between the two conversion.

Indeed, there is:

DGCube("2a_PQ4000_HLG_mode-nar_in-nar_out-nar_nocomp.cube", in="full", lut="full", out="full")

Are those fmtconv lines still valid?

Yes, if you want to mimic as close as possible the zimg calls.
