* - 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.
