gtkDragSetDefaultIcon
Changes the default drag icon. GTK+ retains references for the
arguments, and will release them when they are no longer needed.
WARNING: gtk_drag_set_default_icon is deprecated and should not be used in newly-written code. Change the default drag icon via the stock system by 
changing the stock pixbuf for GTK_STOCK_DND instead.
