* gtk/gtkrc.h: add xthickness and ythickness to GtkRcStyle and
add the necessary tokens.
* gtk/gtkrc.c (gtk_rc_style_init): properly initiality the rc style.
(gtk_rc_style_to_style): copy thicknesses.
(gtk_rc_init_style): apply thicknesses.
(gtk_rc_parse_style): parse xthickness and ythickness.
* gdk/x11/gdkdnd-x11.c: silence compiler in switch() statements.
