Int this example, there are two surfaces, the back ground surface is a blue rectangle in the center of the frame, the overlay surface is full screen red. If this example runs correctly, you can see two rectangles(a smaller blue rectangle in the screen center, and a larger red rectangle), the alpha value of the two rectangles change.
