This sample demonstrates the ability to move an object and work with
lights. "Home" button is pressed and the light bulb next to
the button is turned on.
Two lights are used to create the effect of the turned-on light
bulb:
H-point - point light source provides highlighting of the objects in
the scene by the light bulb
H-spot - spot light source is directed towards the light bulb; it
creates a bright light spot
