 *
 *   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_callback_int3(const char* pstr, int* ptr, int minValue, int maxValue, menuFunc_t callback); // edit int with callback

/**
 * Update the LCD, read encoder buttons, etc.
 *   - Read button states

 *   - Update the encoder position
 *   - Apply acceleration to the encoder position
 *   - Set lcdDrawUpdate = LCD_DRAW_UPDATE_CALL_REDRAW 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 != LCD_DRAW_UPDATE_NONE
 *   - Before calling the handler, LCD_DRAW_UPDATE_CALL_NO_REDRAW => LCD_DRAW_UPDATE_NONE
 *   - Call the menu handler. Menu handlers should do the following:
 *     - If a value changes, set lcdDrawUpdate to LCD_DRAW_UPDATE_CALL_REDRAW
 *     - if (lcdDrawUpdate) { redraw }
 *     - Before exiting the handler set lcdDrawUpdate to:
 *       - LCD_DRAW_UPDATE_CALL_REDRAW or LCD_DRAW_UPDATE_NONE for no callbacks until the next controller event.
 *       - LCD_DRAW_UPDATE_CLEAR_CALL_REDRAW to clear screen, LCD_DRAW_UPDATE_CALL_REDRAW on the next loop.
 *       - LCD_DRAW_UPDATE_CALL_NO_REDRAW for a callback with no forced redraw on the next loop.
 *     - NOTE: For some displays, the menu handler may be called 2 or more times per loop.
 *
 *   After the menu handler callback runs (or not):
 *   - Clear the LCD if lcdDrawUpdate == LCD_DRAW_UPDATE_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.
