Well, we can add some sugar API around the gtk clipboard stuff, but
I'm not sure there's a lot of value in there, as the gtk+ API is
already quite high level.
The problem here is how do we extend the existing X specs to deliver
the experience we aim for. Last we talked about it, Marco was opposed
to use the X selection targets to pass titles and icons around.
Eben, now is a good moment to start talking about it, can you
summarize what is missing from the clipboard and try to list all that
we want to do but the current spec doesn't allow to?
