WebP images with alpha channel renders in poor quality in the Emacs.
If I convert webp image to png, quality is ok in resulting image. Also, if I add webp as native image under MacOS (requires Emacs patch) then quality is also ok.
Looks like partial transparency is incorrectly applied for webp images.
Thanks
