1127 Setting the transient_for to Root is actually illegal, however
1128 applications from time have done this to specify transient for
1131 Now you can do that by being a TYPE_DIALOG and not setting
1132 the transient_for hint at all on your window. But people still
1133 use Root, and Kwin is very strange in this regard.
1135 KWin 3.0 will not consider windows with transient_for set to
1136 Root as transient for their group *UNLESS* they are also modal.
1137 In that case, it will make them transient for the group. This
1138 leads to all sorts of weird behavior from KDE apps which are
1139 only tested in KWin. I'd like to follow their behavior just to
1140 make this work right with KDE stuff, but that seems wrong.
