The specification for those hints says that you must pass in bitmaps for
the icon, although most modern window managers that do iconification
handle pixmaps as well.

If you want to have a multi colour icon that works with all window
managers, you should set the icon_window argument to gdk_window_set_icon,
and handle repaints for that window (or set its background pixmap and mask
appropriately).
