disable custom log handler and fatal mask for now
2002-02-06 Havoc Pennington <hp@pobox.com> * src/main.c (main): disable custom log handler and fatal mask for now * src/theme.c (meta_draw_op_list_draw): Add META_DRAW_CLIP * src/main.c: load theme, monitor current theme setting * src/prefs.c: add "current theme" setting * src/stack.c (meta_stack_free): don't try to free last_root_children_stacked if it doesn't exist * src/themewidget.c: pluggable GtkMisc subclass to use for menu icons * src/screen.c (meta_screen_manage_all_windows): fix signed/unsigned warning * src/frames.c: port to theme system (meta_frames_style_set): chain up * theme-format.txt: new file * configure.in: add more compiler warnings * src/theme.c: add various stuff needed to get theme parser working. Remove the "spacer" concept from FrameLayout object. Add draw op that references a draw op list. * configure.in: require GTK 1.3.13 * src/Makefile.am: add theme-parser.[hc], implement loading a theme * src/theme.c: add "draw title" and "draw window icon" operations (meta_draw_op_draw): put object_width/object_height in expression environment before computing x/y. Handle out-of-memory when creating pixbufs. Assorted other cleanups.
