Change _NET_WM_WINDOW_TYPE on the fly

[Yen-Ju Chen]

I notice that openbox3 only read _NET_WM_WINDOW_TYPE when it starts.
Therefore, I cannot change _NET_WM_WINDOW_TYPE of my program after openbox.
I know it is a rare situation.
But it is useful if I want to drag a program and "dock" it on the side
of screen.
In this case, the window type change from _NET_WM_WINDOW_TYPE_NORMAL
to _NET_WM_WINDOW_TYPE_DOCK.
Can openbox support changing the window type on the fly ?
Thanx.
