If you are using supported versions of GTK+ (2.2.x),
then just use GdkPixbuf and preferrably PNG files instead
of GdkPixmap and XPMs.

If you are using obsolete versions of GTK+ (1.2.x),
then the message means just what it says - when you create
a pixmap, you need to either pass in a non-NULL window
to gdk_pixmap_create_from_xpm() or a non-NULL colormap
to gdk_pixmap_colormap_create_from_xpm().
