Targets with HAVE_LCD_ENABLE: Provide a means to receive notifications when the lcd is enabled and the image is refreshed so overlayed drawing can also be refreshed. Chiefly mpegplayer needs this so it can redraw the YUV data after the backlight is turned on while paused or when using 'Set Start Time'.
