1126 Setting the transient_for to Root is actually illegal, however
1127 applications from time have done this to specify transient for
1130 Now you can do that by being a TYPE_DIALOG and not setting
1131 the transient_for hint at all on your window. But people still
1132 use Root, and Kwin is very strange in this regard.
1134 KWin 3.0 will not consider windows with transient_for set to
1135 Root as transient for their group *UNLESS* they are also modal.
1136 In that case, it will make them transient for the group. This
1137 leads to all sorts of weird behavior from KDE apps which are
1138 only tested in KWin. I'd like to follow their behavior just to
1139 make this work right with KDE stuff, but that seems wrong.
