             * This animation class is used to animate a CSS sprite (moving a background
             * image).  This moves through a series of images in a single image sprite and
             * loops the animation when done.  You should set up the
             * {@code background-image} and size in a CSS rule for the relevant element.
             *
             * @param {Element} element The HTML element to animate the background for.
             * @param {goog.math.Size} size The size of one image in the image sprite.
             * @param {goog.math.Box} box The box describing the layout of the sprites to
             *     use in the large image.  The sprites can be position horizontally or
             *     vertically and using a box here allows the implementation to know which
             *     way to go.
             * @param {number} time The duration in milliseconds for one iteration of the
             *     animation.  For example, if the sprite contains 4 images and the duration
             *     is set to 400ms then each sprite will be displayed for 100ms.
             * @param {function(number) : number=} opt_acc Acceleration function,
             *    returns 0-1 for inputs 0-1.  This can be used to make certain frames be
             *    shown for a longer period of time.
