Description   The background() function sets the color used for the background of the Processing window. The default background is light gray. In the loop() function, the background color is used to refresh the display window between frames. It is possible to load a JPG or GIF image as the background by loading an image which is the same size as the display window. The image must be in the data directory of the sketch for it to load properly.
