WebP Image Format

So I had a feature request to add webp image support to Tectonicus to cut down on the file size of the output. I’ve been aware of webp for a while, but not really paid much attention to it - mostly because it seems to only be supported in Chrome and Opera right now.

Has anyone any experience with webp (both as a user and an app developer)? I found this imageio plugin which says it added webp support to ImageIO, so I’m going to give that a try. There’s also mention of a javascript hack to add support to other browsers, but I’ve not tried it.

Thoughts?

Last I had a look at WebP I didn’t find the file size savings and quality change to be of much significance when compared to png, jpeg, dxt, etc. Also the lack of support for it in most tools and programs is just an additional hassle.
