You're right.

No I've read ICCCM sec 4. It says that the window's icon is drawn when
the state is iconic. So it's better to introduce a new user option
in Sawfish which allows to assume that "Withdrawn + icon window ->
draw that icon".

In the meantime, if Window Maker has been doing so for a decade, and
it's ok, then it must be virtually ok.

(A window manager doesn't have to draw icons. If it does, it's a
feature.)

But you don't have to care about such new option. I can take that
part, so you can concentrate on icon.

Strictly speaking, you're right; icon windows are quite different,
whose most properties are ignored. But in our case, it's a workaround,
so adding some hacks may suffice.

Together with ICCCM, now I'm sure that it's better to collect all lisp
codes into one file, wm.state.dockapp or wm.ext.dockapp.

For reference use of this message, let me point out that if 
_NET_WM_HANDLED_ICON is set to a window, then the wm doesn't have to
provide an icon for that window.
