It makes sense and your modification works. Thanks!

But actually, the speed is very slow. When I drew the rectangle just by
calling putPixel on appropriate points, on 2.5 GHz machine, even after
compilation with -O2 switch it worked slowly. I suppose that my old 33 Mhz
machine with a similar program in Pascal would do better. Of course, Haskell
is not fast, but this was way too slow for the computer of these
capabilities. Any ideas what's the reason?
