Detailed Description

Define GLUT popup menus with callbacks simulated as keyboard events.

Use AddItem(doc-str, callback, hot-key, [converted-key]) to register a menu item.

When the registered item is clicked, the 'hot-key', or an auto-generated key if it is not given, is sent to the embedded KeyBorad object, which will call 'callback' with 'converted-key', which ususally is item_id or menu_id*MAX_ITEM + item_id as the parameter. The 'converted-key', however, does not necessary related to menu-item-id, and can actually be customized to specific requirement as in the implementation of ControlGroup.

If the hot-key, or the auto-generated-key (usually non printing though), is pressed, the 'callback' of this menu item is also called with the menu item id as the parameter, together with x and y positions of key event.
