138 //
139 // the following changes were made:
140 // 1. for the permutation indexing (r[] array in this code) I substituted
141 // the ^ operator (which never overflows) for the original addition and
142 // masking code, this should not have any effect on quality.
143 // 2. removed the outermost randomization array lookup.
144 // (it really wasn't necessary, it's fine if X indexes the array
145 // directly without permutation indexing)
146 // 3. reimplemented the blending using frac[] arrays rather than a macro.
147 // (the original macro read one parameter twice - not good)
148 // 4. cleaned up the code by using 4 nested loops to make it read nicer
149 // (but then I unrolled it completely for speed, it still looks nicer).
