http://standards.freedesktop.org/wm-spec/wm-spec-1.4.html#id2512420
Implementing enhanced support for application transient windows
If the WM_TRANSIENT_FOR property is set to None or Root window, the
window should be treated as a transient for all other windows in
the same group. It has been noted that this is a slight ICCCM
violation, but as this behavior is pretty standard for many
toolkits and window managers, and is extremely unlikely to break
anything, it seems reasonable to document it as standard. */
