Lots of dumb crap to do... something. Instead of adding yet another dumb helper, just use the main" sws_utils API in both callers. (Which, unfortunately, has been duplicated for glorious webp screenshots, despite the fact that webp is crap.) Good part: can enable zimg for screenshots (as far as needed). Bad part: uses "default" swscale parameters instead of HQ now.
