Ahah - maybe they should be asserts then. The thing was that I was getting
one firing from the function doc script, because (snoise) was calling
noise(), with the wrong number of arguments, which I fixed afterwards...

So IIRC simplex noise has less of the artifacts of perlin noise (which
looks a bit blocky due to the regular sampling) but simplex noise is a bit
slower...

cheers,
