+ * samplerBuffer       KEYWORD(130, 0, 140, 0, SAMPLERBUFFER)

  * - a reserved word - error                 ...in GLSL >= 1.30

 Computing the result is then simply a matter of convolving all the
 pixels starting at k with all the samples in the matrix.
+
+
+--- SEPARABLE_CONVOLUTION
+
+For this filter, x is first rounded to one of n regularly spaced
+subpixel positions. This subpixel position determines which of n
+convolution matrices is being used.
+
+Then, as in a regular convolution filter, the first pixel to be used
+is determined:
+
+    	k = floor (x - (width - 1) / 2.0 - e)
+
+and then the image pixels starting there are convolved with the chosen
+matrix. If we write x = xi + frac, where xi is an integer, we get
+
+	k = xi + floor (frac - (width - 1) / 2.0 - e)
+
+so the location of k relative to x is given by:
+
+    (k + 0.5 - x) = xi + floor (frac - (width - 1) / 2.0 - e) + 0.5 - x
+
+                  = floor (frac - (width - 1) / 2.0 - e) + 0.5 - frac
+
+which means the contents of the matrix corresponding to (frac) should
+contain width samplings of the function, with the first sample at:
+
+       floor (frac - (width - 1) / 2.0 - e) + 0.5 - frac
+
+This filter is called separable because each of the k x k convolution
+matrices is specified with two k-wide vectors, one for each dimension,
+where each entry in the matrix is computed as the product of the
+corresponding entries in the vectors.

+ * This file provides a fast SIMD-optimized noncryptographic PRNG (pseudorandom
+ * number generator), with the output good enough to pass "Big Crush" tests
+ * from TestU01 (http://en.wikipedia.org/wiki/TestU01).
+ *
+ * SIMD code uses http://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html
+ * which is a GCC specific extension. There is also a slower alternative
+ * code path, which should work with any C compiler.
+ *
+ * The "prng_t" structure keeps the internal state of the random number
+ * generator. It is possible to have multiple instances of the random number
+ * generator active at the same time, in this case each of them needs to have
+ * its own "prng_t". All the functions take a pointer to "prng_t"
+ * as the first argument.
+ *
+ * Functions:
+ *
+ * ----------------------------------------------------------------------------
+ * void prng_srand_r (prng_t *prng, uint32_t seed);
+ *
+ * Initialize the pseudorandom number generator. The sequence of preudorandom
+ * numbers is deterministic and only depends on "seed". Any two generators
+ * initialized with the same seed will produce exactly the same sequence.
+ *
+ * ----------------------------------------------------------------------------
+ * uint32_t prng_rand_r (prng_t *prng);
+ *
+ * Generate a single uniformly distributed 32-bit pseudorandom value.
+ *
+ * ----------------------------------------------------------------------------
+ * void prng_randmemset_r (prng_t                  *prng,
+ *                         void                    *buffer,
+ *                         size_t                   size,
+ *                         prng_randmemset_flags_t  flags);
+ *
+ * Fills the memory buffer "buffer" with "size" bytes of pseudorandom data.
+ * The "flags" argument may be used to tweak some statistics properties:
+ *    RANDMEMSET_MORE_00 - set ~25% of bytes to 0x00
+ *    RANDMEMSET_MORE_FF - set ~25% of bytes to 0xFF
+ * The flags can be combined. This allows a bit better simulation of typical
+ * pixel data, which normally contains a lot of fully transparent or fully
+ * opaque pixels.
