/** \file
* Menu structures and functions.
*
* When adding a menu item, the convention in the Magic Lantern menus
* is that there are 12 characters for the label and up to 7 characters
* for the value. The box that is drawn is 540 pixels wide, enough
* for 19 characters in FONT_LARGE.
*
* There is room for 8 entries in the menu.
*
* New menus must have a 5 character top level name.
