// a cross-platform model for this special menu, but on the Mac it's easier to
// get spacing and alignment precisely right using a NIB. To do that, we
// subclass the generic MenuController implementation and special-case the two
// items that require specific layout and load them from the NIB.

// manner. To avoid those headaches, tests should provide an alternative
// implementation.
