-Notes on program parameters, etc.
-
-The instructions we emit will use six kinds of source registers:
-
- PROGRAM_INPUT - input registers
- PROGRAM_TEMPORARY - temp registers
- PROGRAM_ADDRESS - address/indirect register
- PROGRAM_SAMPLER - texture sampler
- PROGRAM_CONSTANT - indexes into program->Parameters, a known constant/literal
- PROGRAM_STATE_VAR - indexes into program->Parameters, and may actually be:
- + a state variable, like "state.fog.color", or
- + a pointer to a "program.local[k]" parameter, or
- + a pointer to a "program.env[k]" parameter
-
-Basically, all the program.local[] and program.env[] values will get mapped
-into the unified gl_program->Parameters array. This solves the problem of
-having three separate program parameter arrays.

- * \author Stefan Gustavson (stegu@itn.liu.se)
- *
- *
- * 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

- * 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,
- * repeated twice to avoid wrapping the index at 255 for each lookup.
- * 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 int[] instead of a char[] 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!
