 * This is a buttonbox that swaps button order based on platform defaults.
 *
 * This file fixes the DialogButtonBox having really bad defaults.
 * Specifically, it doesn't align the buttons right, but uses the
 * full width (making the buttons too big).
 * It doesn't have any spacing between the buttons.
 * Also it removes spacing above and below that should not be there.
