	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.

	* src/Makefile.am: add theme-parser.[hc], implement loading a
	theme
