IMNSHO child frame support (on X) is actually a misfeature, and
completions should be implemented with an override-redirect toplevel
window instead.

The reasoning behind this conclusion is the sheer amount of code we
spend trying to force toolkits (GTK in particular, but also Xt) and the
X server (in the case of the X input extension) to play nice with
supposedly "toplevel" windows being a child of an actual toplevel
