Correctness

The D implementation generates exactly the same outputs of the Java version. I have used the D code to generate this image (with the grayscale code visible in the D entry): http://oi62.tinypic.com/2pt9flx.jpg

Is such image correct? Isn't a correct Perlin noise image without sharp borders, like this?
