        Button-reordering patch. Has all the code except actually
	installing a gconf schema and reading the gconf key in prefs.c.
	metacity-theme-viewer displays the button layouts for testing
	themes.

	* src/preview-widget.c (meta_preview_size_request): make up a
	width/height if no child widget

	* src/prefs.c (meta_prefs_get_button_layout): new function

	* src/frames.c: get the button layout from prefs and
	use it when drawing

	* src/theme.c (meta_frame_layout_calc_geometry): enhance to be
	able to lay out buttons in different arrangements
	(button_rect): draw the new button background rectangles
	(meta_theme_draw_frame): require a button layout argument
	(meta_theme_calc_geometry): pass in the button layout

	* src/preview-widget.h: mod to handle button layouts

	* src/theme-viewer.c: mod to handle button layouts
