Comment 60 for bug 842566

snowguy, thanks to your comments, I've been able to correctly match also the transient windows like the Writer's styles window.

Now it's matched as a sub-window of the writer, and so the alt+tab will work fine.
However, don't use the new code that I've just pushed on my branch since I don't think that it will work well with alt+tab/` in oneiric (it will be worst, in fact).
To get that you'll need another unity branch that I'm working on.
