 // DialogClientView
 //
 //  This ClientView subclass provides the content of a typical dialog box,
 //  including a strip of buttons at the bottom right of the window, default
 //  accelerator handlers for accept and cancel, and the ability for the
 //  embedded contents view to provide extra UI to be shown in the row of
 //  buttons.
 //
 //  DialogClientView also provides the ability to set an arbitrary view that is
 //  positioned beneath the buttons.
