New function to reset the RC styles for a heirarchy

Fri May  1 12:06:43 1998  Owen Taylor  <otaylor@gtk.org>

	* gtk/gtkwindow.[ch] (gtk_widget_reset_rc_styles): New
	function to reset the RC styles for a heirarchy

        Clear the window background if necessary in
	gtk_window_style_set.

	* gtk/gtkrc.[ch]: New function gtk_rc_reparse_all() which
	rereads all previously read RC files.

	* gdk/gdkwindow.c gdk/gdk.h: New function gdk_window_get_toplevels().
	(Should it just be called gdk_get_toplevels?)

	* gtk/testgtk.c: New test to reload RC files.
