Comment 8 for bug 460483

Geoff, sorry for my ignorance, but could you explain in more details why exactly your current
code for hiding the windows needs to be hacky? Doesn't Gtk have some kind of "hide window"
function that can be connected to the close button? Or the problem is that this isn't possible
to do through the API exposed to the plugins?

The second link in the bug report (http://blog.sukimashita.com/?p=124) seems to need very
little code, but apparently it relies on a function that was deprecated.
