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.
