Ah, that is what it was for.  Well, there were problems with
the DnD code in finding the xdnd properties on windows.   So
I rewrote sometime the code to find the XWindow with the xdnd
properties attached.

I think that we still might need it when we want DnD to work
between GNUstep and non GNUstep applications.   GNUstep
is very forgiving w.r.t. on which window the xdnd properties
are set.  But others programs might not be so forgiving and
we have to set the properties on the right window for them.
