GTK+ doesn't use separate pixbufs for those type of icons, but generates
them on the fly with gdk_pixbuf_saturate_and_pixelate().

new_pixbuf = gdk_pixbuf_copy (original);
gdk_pixbuf_saturate_and_pixelate(original, new_pixbuf, 0.8, TRUE);

And then set "new_pixbuf" as the image for the status icon. This will be
a bit convoluted in the actual code as you're using icon names, and we'd
need to 1) know whether we have a killswitch, and whether it's enabled
and 2) modify the status icon to use the pixbuf.
