* http://webstaff.itn.liu.se/~stegu/simplexnoise/SimplexNoise.java:
* - Based on example code by Stefan Gustavson (stegu@itn.liu.se).
* - Optimisations by Peter Eastman (peastman@drizzle.stanford.edu).
* - Better rank ordering method by Stefan Gustavson in 2012.
*
* This implementation is "Simplex Noise" as presented by
* Ken Perlin at a relatively obscure and not often cited course
* session "Real-Time Shading" at Siggraph 2001 (before real
* time shading actually took on), under the title "hardware noise".
* The 3D function is numerically equivalent to his Java reference
* code available in the PDF course notes, although I re-implemented
* it from scratch to get more readable code. The 1D, 2D and 4D cases
* were implemented from scratch by me from Ken Perlin's text.

* Permutation table. This is just a random jumble of all numbers 0-255.
*
* This produce a repeatable pattern of 256, but Ken Perlin stated
* that it is not a problem for graphic texture as the noise features disappear
* at a distance far enough to be able to see a repeatable pattern of 256.
*
* This needs to be exactly the same for all instances on all platforms,
* so it's easiest to just keep it as static explicit data.
* This also removes the need for any initialisation of this class.
*
* Note that making this an uint32_t[] instead of a uint8_t[] might make the
* code run faster on platforms with a high penalty for unaligned single
* byte addressing. Intel x86 is generally single-byte-friendly, but
* some other CPUs are faster with 4-aligned reads.
* However, a char[] is smaller, which avoids cache trashing, and that
* is probably the most important aspect on most architectures.
* This array is accessed a *lot* by the noise functions.
* A vector-valued noise over 3D accesses it 96 times, and a
* float-valued 4D noise 64 times. We want this to fit in the cache!
