Has anyone successfully build webp encoder for wasm?

I haven't tried building libwebp on wasm, though FYI were going to be dropping the dependency: #1984

[sekoyo]

Oh that would be great. I found most converters online even on supposedly 100% quality lost noticeable image quality PNG->WEBP, I had to go through about 5 to find one that didn't, so lossless is great, though I see their use case for lossy too and as a general tool to provide more options to a user converting.

I'll try and debug and figure out what's up with the C one to wasm.
