  /**
   *
   * Functions for editing single values
   *
   * The "menu_edit_type" macro generates the functions needed to edit a numerical value.
   *
   * For example, menu_edit_type(int, int3, itostr3, 1) expands into these functions:
   *
   *   bool _menu_edit_int3();
   *   void menu_edit_int3(); // edit int (interactively)
   *   void menu_edit_callback_int3(); // edit int (interactively) with callback on completion
   *   static void _menu_action_setting_edit_int3(const char* pstr, int* ptr, int minValue, int maxValue);
   *   static void menu_action_setting_edit_int3(const char* pstr, int* ptr, int minValue, int maxValue);
   *   static void menu_action_setting_edit_callback_int3(const char* pstr, int* ptr, int minValue, int maxValue, screenFunc_t callback); // edit int with callback
   *
   * You can then use one of the menu macros to present the edit interface:
   *   MENU_ITEM_EDIT(int3, MSG_SPEED, &feedrate_multiplier, 10, 999)
   *
   * This expands into a more primitive menu item:
   *   MENU_ITEM(setting_edit_int3, MSG_SPEED, PSTR(MSG_SPEED), &feedrate_multiplier, 10, 999)
   *
   *
   * Also: MENU_MULTIPLIER_ITEM_EDIT, MENU_ITEM_EDIT_CALLBACK, and MENU_MULTIPLIER_ITEM_EDIT_CALLBACK
   *
   *       menu_action_setting_edit_int3(PSTR(MSG_SPEED), &feedrate_multiplier, 10, 999)

 *     - If a value changes, set lcdDrawUpdate to LCDVIEW_REDRAW_NOW and draw the value
 *       (Encoder events automatically set lcdDrawUpdate for you.)
 *     - if (lcdDrawUpdate) { redraw }

 *       - LCDVIEW_REDRAW_NOW or LCDVIEW_NONE to keep drawingm but only in this loop.

 *     - NOTE: For graphical displays menu handlers may be called 2 or more times per loop,
 *             so don't change lcdDrawUpdate without considering this.
 *
 *   After the menu handler callback runs (or not):
 *   - Clear the LCD if lcdDrawUpdate == LCDVIEW_CLEAR_CALL_REDRAW
 *   - Update lcdDrawUpdate for the next loop (i.e., move one state down, usually)
