resources when redrawing is required. A passive slider doesn't require a
lot of CPU (if at all), but it does when you move it. The more complex the
GUI element, the more power is required. One typical use of GUI you want to
avoid if your machine has limited resources is long arrays that would be
redrawn all the time (like in an oscilloscope).
