 * for the buttons. The dialog is not yet shown, so that the
 * caller can add additional buttons or make other visual changes
 * without causing flashiness.
 * @question: The text of the question.
 * @answer_0: The label of the leftmost button (index 0)
 * @answer_1: The label of the 2nd-to-leftmost button (index 1)
 * @parent: The parent window for this dialog.
