1134 Setting the transient_for to Root is actually illegal, however
1135 applications from time have done this to specify transient for
1138 Now you can do that by being a TYPE_DIALOG and not setting
1139 the transient_for hint at all on your window. But people still
1140 use Root, and Kwin is very strange in this regard.
1142 KWin 3.0 will not consider windows with transient_for set to
1143 Root as transient for their group *UNLESS* they are also modal.
1144 In that case, it will make them transient for the group. This
1145 leads to all sorts of weird behavior from KDE apps which are
1146 only tested in KWin. I'd like to follow their behavior just to
1147 make this work right with KDE stuff, but that seems wrong.
