This function is equivalent to gif_file() but works for animations encoded
as a sprite. A sprite is a single image file where each frame of the
animation is stacked next to each other. The animation then happens by
changing what slice of the image is shown. The implementation used allow
users to click on the animation in order to toggle pause/play.
