Sets the icon of window as a pixmap or window. If using GTK+, investigate
gtk_window_set_default_icon_list() first, and then gtk_window_set_icon_list()
and gtk_window_set_icon(). If those don't meet your needs, look at
gdk_window_set_icon_list(). Only if all those are too high-level do you
want to fall back to gdk_window_set_icon().
