It's rather moot, as this isn't a movie at 25fps, so an occasional image 
refresh, no matter how it's done, will take magnitudes less energy per time in 
average, than the backlight eats to display the image. When screen is dimmed 
(or the widget invisible/hidden/background) then of course all gfx workload 
should suspend, for obvious reasons
