	* capplets/new-background-properties/applier.c (set_root_pixmap):
	If the passed pixmap is None, delete the root pixmap properties
	and don't try to set the background on the root window
	(is_nautilus_running): Implement. Return TRUE iff Nautilus is
	running, FALSE otherwise
	(applier_apply_prefs): If Nautilus is running and we are rendering
	to the root pixmap, just remove the root pixmap window property
	(renderer_render_to_screen): Set root pixmap to None (i.e.,
	destroy root pixmap) if we're rendering a solid background to the
	root window
