This is an example of how to make actors appear to move beyond the boundaries of a world,
by making the background scroll. In this example a helicopter flies around a panoramic
image of the Bronx Zoo.
You can substitute any background image you like by editing ScrollWorld.java and setting
the constant PANORAMA_FILENAME to the name of your background image (by default
it should be in the images directory).
There are named constants to define whether your image is a 360-degree panorama in the
horizontal or vertical directions. If a constant is true, the image will be repeated in that
direction so the helicopter can keep flying forever in the same direction.
