* probably want to set up the drag icon using the surface returned
* by gdk_drag_get_drag_surface().
*
* This function returns a reference to the GdkDrag object, but GTK
* keeps its own reference as well, as long as the DND operation is
* going on.
*
* Note: if @actions include %GDK_ACTION_MOVE, you need to listen for
* the #GdkDrag::dnd-finished signal and delete the data at the source
* if gdk_drag_get_selected_action() returns %GDK_ACTION_MOVE.
