Arrangement of buttons on the titlebar. The value should be a string, such as "menu:minimize,maximize,spacer,close"; the colon separates the left corner of the window from the right corner, and the button names are comma-separated. Duplicate buttons are not allowed. Unknown button names are silently ignored so that buttons can be added in future metacity versions without breaking older versions. A special spacer tag can be used to insert some space between two adjacent buttons.
