Lossless option? #12
Description
I see quality can be controlled up to 100 (least lossy) but webp has two different "modes" and 100% quality is not the same as lossless and in fact for areas where a transparent png is the best non-webp format, usually webp lossless is superior (file size and quality) to webp lossy 100%.
Is there a way to enable lossless?
It might also be good to be able to configure webp settings per file type - so I can have different settings for my pngs (graphics) than for my jpegs (photos) as it is likely there is not a single set of rules that would compress both types well.
