 // The Wrench menu has a creative layout, with buttons in menu items. There is
 // 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.
 //
 // This object is owned by the ToolbarController and receives its NIB-based
 // views using the shim view controller below.
