I remember being this impossible but I don't remember all the
issues. Owen will know.

You can use XGetSelectionOwner() to see if someone owns the selection
(i.e. there's something to paste), but I don't think there's a good
way to know whether the available stuff to paste is something you know
how to paste. i.e. you can't find out the data types of the stuff on
the clipboard (text, image, postscript, Word document) without
actually trying to paste. I could be wrong.
