	* gdk/x11/gdkprivate-x11.h (XID_FONT_BIT):
	* gdk/x11/gdkfont-x11.c:
	* gdk/x11/gdkxid.c: Use an unused high bit in the
	XID to mark fonts in the global xid hash table.

	* gdk/x11/gdkcursor-x11.c (update_cursor): Skip fonts
	when iterating over the xid hash table, since calling
	GDK_IS_WINDOW () on an GdkFont can cause a segfault.
