/**
 *
 * 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, menuFunc_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

/**
 * Update the LCD, read encoder buttons, etc.
 *   - Read button states
 *   - Check the SD Card slot state
 *   - Act on RepRap World keypad input
 *   - Update the encoder position
 *   - Apply acceleration to the encoder position
 *   - Set lcdDrawUpdate = LCDVIEW_CALL_REDRAW_NOW on controller events
 *   - Reset the Info Screen timeout if there's any input
 *   - Update status indicators, if any
 *
 *   Run the current LCD menu handler callback function:
 *   - Call the handler only if lcdDrawUpdate != LCDVIEW_NONE
 *   - Before calling the handler, LCDVIEW_CALL_NO_REDRAW => LCDVIEW_NONE
 *   - Call the menu handler. Menu handlers should do the following:
 *     - If a value changes, set lcdDrawUpdate to LCDVIEW_REDRAW_NOW and draw the value
 *       (Encoder events automatically set lcdDrawUpdate for you.)
 *     - if (lcdDrawUpdate) { redraw }
 *     - Before exiting the handler set lcdDrawUpdate to:
 *       - LCDVIEW_CLEAR_CALL_REDRAW to clear screen and set LCDVIEW_CALL_REDRAW_NEXT.
 *       - LCDVIEW_REDRAW_NOW or LCDVIEW_NONE to keep drawingm but only in this loop.
 *       - LCDVIEW_REDRAW_NEXT to keep drawing and draw on the next loop also.
 *       - LCDVIEW_CALL_NO_REDRAW to keep drawing (or start drawing) with no redraw on the next 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)
 *
 * No worries. This function is only called from the main thread.
