    // cause the browser object to be destroyed immediately. Return true (1) if
    // the browser is parented to another window and that other window needs to
    // receive close notification via some non-standard technique.
    //
    // If an application provides its own top-level window it should handle OS
    // close notifications by calling cef_browser_host_t::CloseBrowser(false (0))
    // instead of immediately closing (see the example below). This gives CEF an
    // opportunity to process the 'onbeforeunload' event and optionally cancel the
    // close before do_close() is called.
    //
    // The cef_life_span_handler_t::on_before_close() function will be called
    // immediately before the browser object is destroyed. The application should
    // only exit after on_before_close() has been called for all existing
    // browsers.
    //
    // If the browser represents a modal window and a custom modal loop
    // implementation was provided in cef_life_span_handler_t::run_modal() this
    // callback should be used to restore the opener window to a usable state.
    //
    // By way of example consider what should happen during window close when the
    // browser is parented to an application-provided top-level OS window. 1.
    // User clicks the window close button which sends an OS close
    //     notification (e.g. WM_CLOSE on Windows, performClose: on OS-X and
    //     "delete_event" on Linux).
    // 2.  Application's top-level window receives the close notification and:
    //     A. Calls CefBrowserHost::CloseBrowser(false).
    //     B. Cancels the window close.
    // 3.  JavaScript 'onbeforeunload' handler executes and shows the close
    //     confirmation dialog (which can be overridden via
    //     CefJSDialogHandler::OnBeforeUnloadDialog()).
    // 4.  User approves the close. 5.  JavaScript 'onunload' handler executes. 6.
    // Application's do_close() handler is called. Application will:
    //     A. Set a flag to indicate that the next close attempt will be allowed.
    //     B. Return false.
    // 7.  CEF sends an OS close notification. 8.  Application's top-level window
    // receives the OS close notification and
    //     allows the window to close based on the flag from #6B.
    // 9.  Browser OS window is destroyed. 10. Application's
    // cef_life_span_handler_t::on_before_close() handler is called and
    //     the browser object is destroyed.
