If I use tostring I get a string which I can put on the clipboard, but
it isn't any kind of image. I can make a PIL image from the string but
them I'm back to square one again.

I suppse I could save the image object to a real file and then send
that to the clipboard, but that seems wasteful and I'd have to worry
about what to call it and where to put it. Much neater if I could just
create it in memory somehow.
