Any chance of testing more inbuilt chroma scalers? #16

Particularly interested in Hamming, Kaiser and maybe Catmull_Rom (mainly since it more well known).

Upscaling is upscaling, it doesn't really matter that you're resampling a chroma plane. I've already covered most if not all filters available in mpv: https://artoriuz.github.io/blog/imagemagick_resampling.html

It's not quite a simple as that, maybe it is for the automatic tools but subjectively they produce a different variance of artifacts and some types of artifacts aren't seen as much in chroma scaling than luma scaling. I'd still be interested in what the automatic tools think, even if it's just for the ones I listed.
