That's what we do today. We support those three image formats with
native code, and others can be supported by a js implementation, which
anyone can write.
*Can* anyone, though?
From an extension, to be clear.
As in, an extension can implement an image decoder for a new image
format, and imagelib will use it. All the rest of the image-loading
stuff will work as it already does and be handled by Gecko.
Doing that sort of thing from untrusted script is obviously a different
question altogether...
