I have one question about this: WM_CLASS can be set on a window's
"leader", Y, and this value would be used in place of the WM_CLASS
hint set on any other window X which sets a WM_CLIENT_LEADER to Y [1].

Does Window Maker use the leader's WM_CLASS hint to check for
"DockApp" when WM_CLIENT_LEADER is set?  It would be unpleasant to not
follow the same conventions.  But also, to not follow the convention
of the WM_CLASS property in this instance.
