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
