* - If a value changes, set lcdDrawUpdate to LCD_DRAW_UPDATE_CALL_REDRAW
* - If a value changes, set lcdDrawUpdate to LCDVIEW_REDRAW_NOW
* - 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.

* - Clear the LCD if lcdDrawUpdate == LCD_DRAW_UPDATE_CLEAR_CALL_REDRAW
* - Clear the LCD if lcdDrawUpdate == LCDVIEW_CLEAR_CALL_REDRAW
