We need the window to exist and be mapped otherwise the child won't render it's contents
We also need it to exist in the right place to get the clicks working as GTK will check sendEvent locations to see if our window is in the right place. So even though our contents are drawn via compositing we still put this window in the right place
We can't composite it away anything parented owned by the root window (apparently)
Stack Under works in the non composited case, but it doesn't seem to work in kwin's composited case (probably need set relevant NETWM hint)
As a last resort set opacity to 0 just to make sure this container never appears
