2002-06-08 Havoc Pennington <hp@pobox.com> * src/xprops.c (meta_prop_get_utf8_string): don't die on bad atom name * src/display.c (meta_display_close): don't unmanage windows here, do it in screen_free and then closing the display unmanages windows as a side effect of unmanaging the screen (meta_display_unmanage_screen): new function (process_selection_clear, process_selection_request): handle selection stuff (meta_spew_event): don't crash on client message containing invalid atom (meta_spew_event): don't crash on property notify with invalid atom * src/main.c (main): add --replace option to replace existing window manager. * src/screen.c: implement holding manager selection. * src/display.c (meta_display_open): add new selection-related atoms.
