A static window width was specified in pixels before, which is
"problematic". Then it was ignored and menus were automatically
sized to their largest menu item.
Due to popular demand, add the possibility to specify a minimal
window width in percent of screen width. If set to 0 (default),
menus will autosize as before.
Main menu is set to 22% screenwidth.
