added dirty workaround to open program window on specified display

As SDL function "SDL_GetNumVideoDisplays()" seems to be broken on some
systems (tested with older Linux systems and SDL 2.0.0 and 2.0.6, but
also current macOS with SDL 2.0.20), do not use it for now to check if
the specified display number is valid.
