That works too. I'm having a hard time coming up with any really good
reason to prefer any of these...

Another thought I just had: I don't know why GtkInvisible bothers to
have an input only window anyhow - the window gets positioned
offscreen. So it could just be a visible window. I guess input only is
mildy more efficient on the server, that's all I can think of.
