And, again, I don't see what that has to do with whether the spec mandates
that user agents let apps place JPEG, PNG or GIF directly on the local
system clipboard. The spec doesn't currently mandate OpenEXR be supported,
so it's currently up to individual user agents to decide whether they can
support that format safely.
