I submitted a patch that should ignore encoding prefs but CheckTypeForFile used by decoding info is pretty much unprotected. I'll see if I can patch it as well, but the functions it is calling are used very widely.

Probably bunch of stuff will break. So I'll submit a try before submitting this for review.
Also this patch is still going to leak hardware support for WebMDecoder, MP3Decoder and ADTSDecoder, but all the plumbing is done, it is just a matter of if shouldResistFingerprinting, so we just have to decide how do we want to force capabilities.
