I wanted to try creating histograms myself, and my results look different. It
seems when someone wants to use f_noise3d as a random number generator, it
is important to use a big range. I used a unit circle and unit square, and I
thought the difference might be interesting..

(histograms are from 1024x1024 renderings, i reduced resolution and colors
because of file-size)
