/**
 * Format animation controls and add them to a container. This includes

 * 
 * @param container
 *            this container is emptied, assigned a GridBagLayout, and the
 *            other arguments are added to this container.
 * @param togglePlayButton
 *            this button will be the left-most button. It is expected to
 *            always be visible.
 * @param buttons
 *            an optional collection of buttons to display after the
 *            togglePlayButton.
 * @param slider
 *            the slider that stretches to fill the remaining width.
