 * Choicebox uses two groups in theme file, called $group_prefix/item and
 * $group_prefix/footer.
 *
 * Both groups should have data item called 'min_height'. As soon as edje can
 * read the min size from the group, this requirement will be lifted.
 *
 * Items will be sent the following signals:
 * - select, for setting selected state
 * - deselect, for unsetting selected state
 * - set_even, for setting "even" variant of state, if necessary
 * - set_odd, for setting "odd" variant of state, if necessary
 * - empty, for setting "empty" variant of state, for items beyond the end of list
 *
 * Choicebox does not manipulate content of the items, providing callbacks for
 * this.
