 *   - Do refresh(LCDVIEW_CALL_REDRAW_NOW) on controller events

 *   - 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 (should_draw()) { redraw }
 *     - Before exiting the handler set lcdDrawUpdate to:
 *       - LCDVIEW_CLEAR_CALL_REDRAW to clear screen and set LCDVIEW_CALL_REDRAW_NEXT.
 *       - LCDVIEW_REDRAW_NOW to draw now (including remaining stripes).
 *       - LCDVIEW_CALL_REDRAW_NEXT to draw now and get LCDVIEW_REDRAW_NOW on the next loop.
 *       - LCDVIEW_CALL_NO_REDRAW to draw now and get LCDVIEW_NONE 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)
