1158 Setting the transient_for to Root is actually illegal, however
1159 applications from time have done this to specify transient for
1160 their group.
1161
1162 Now you can do that by being a TYPE_DIALOG and not setting
1163 the transient_for hint at all on your window. But people still
1164 use Root, and Kwin is very strange in this regard.
1165
1166 KWin 3.0 will not consider windows with transient_for set to
1167 Root as transient for their group *UNLESS* they are also modal.
1168 In that case, it will make them transient for the group. This
1169 leads to all sorts of weird behavior from KDE apps which are
1170 only tested in KWin. I'd like to follow their behavior just to
1171 make this work right with KDE stuff, but that seems wrong.
