    @class wxSplashScreen

    wxSplashScreen shows a window with a thin border, displaying a bitmap
    describing your application.

    Show it in application initialisation, and then either explicitly destroy
    it or let it time-out.

    Example usage:

    @code
      wxBitmap bitmap;
      if (bitmap.LoadFile("splash16.png", wxBITMAP_TYPE_PNG))
      {
          wxSplashScreen* splash = new wxSplashScreen(bitmap,
              wxSPLASH_CENTRE_ON_SCREEN|wxSPLASH_TIMEOUT,
              6000, NULL, -1, wxDefaultPosition, wxDefaultSize,
              wxBORDER_SIMPLE|wxSTAY_ON_TOP);
      }
      wxYield();
    @endcode
