2002-11-03 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_new): use window-props.h stuff for a couple of properties (implement_showing): fix printf string * src/xprops.c (meta_prop_free_values): new function * src/window-props.h, src/window-props.c: start moving code that handles loading window properties into this file.
