    // 1) a separate NSWindow instance

    //          (if created by Interface Builder: not "Visible at Launch")
    //          (if created in code: must not be ordered front)
    //      - must not be released when closed
    //      - ideally the same size as the view controller's view frame size
    //
    // 2) two separate NSViewController instances
    //      - one for the popover, the other for the detached window
    //      - view best loaded as a sebarate nib (file's owner = NSViewController)
    //
