Changes the icon for a widget to a given widget.
GTK+ will not destroy the icon, so if you don’t want
it to persist, you should connect to the “drag-end”
signal and destroy it yourself.
GTK+ will, however, change the opacity and position of
the window as part of the drag animation. If you want
to reuse the window, you have to restore these to
the values you need after each drag operation.
