The ability to yank DIBV5 will be lost. If there is no alternative such 
as PNG or image/*, then yank can't be done.

It can be binary, but not always.  Is unibyte ok for binary cases? I can 
treat text/* differently, and make exceptions for types like image/svg+xml.

In the binary case, is there any decoding to do?
