Hmm, the only thing is you can only pick up size-changed events once the
size has changed :) Listening to the DBus events would be possible,
though.

Thanks for your interpretation. But the fact that an API needs
interpretation at all is quite a bit funny.

I'm getting the feeling that your interpretation is the right one. Still
I hope you're wrong, that would be probably the most cumbersome API I've
ever seen...
