Setting the transient_for to Root is actually illegal, however
applications from time have done this to specify transient for
their group.
Now you can do that by being a TYPE_DIALOG and not setting
the transient_for hint at all on your window. But people still
use Root, and Kwin is very strange in this regard.
KWin 3.0 will not consider windows with transient_for set to
Root as transient for their group *UNLESS* they are also modal.
In that case, it will make them transient for the group. This
leads to all sorts of weird behavior from KDE apps which are
only tested in KWin. I'd like to follow their behavior just to
make this work right with KDE stuff, but that seems wrong.
