* DEFINE_MENU_EDIT_ITEM_TYPE(int3, int16_t, i16tostr3rj, 1)
*
* Define struct types for use by EDIT_ITEM(...) macros, which encompass
* a primitive storage type, a string function, and a scale factor for edit / display.
* The EDIT_ITEM macros take care of calling action and draw methods as needed.
*
* For example, DEFINE_MENU_EDIT_ITEM_TYPE(percent, uint8_t, ui8tostr4pctrj, 100.f/255.f, +0.5f) expands into:
*
* struct MenuEditItemInfo_percent {
* typedef uint8_t type_t;
* static inline float scale(const_float_t value) { return value * (100.f/255.f) +0.5f; }
* static inline float unscale(const_float_t value) { return value / (100.f/255.f) +0.5f; }
* static inline const char* strfunc(const_float_t value) { return ui8tostr4pctrj(_DOFIX(uint8_t,value)); }
* };
* typedef TMenuEditItem<MenuEditItemInfo_percent> MenuItem_percent
