hm, the most simple way is probably to add a vbox to the
button and add the pixmaps to the vbox.
then do

gtk_container_block_resize (GTK_CONTAINER (pixmap->parent));
gtk_widget_hide (pixmap);
gtk_widget_show (other_pixmap);
gtk_container_unblock_resize (GTK_CONTAINER (pixmap->parent));

i did that in the old version of gemvt and am still doing
it in the status bar, it works perfectly.
