Herb Derby fe678d9b1c change of parameter from [0, 1) to [-1, 1) for better lerp ... Using the extra bit improves the difference rate from .38% to .19%. I think this uses the full resolution of all the values, and there is no more accuracy by trying to get more bits in use. The maximum difference is still 1. This gives the same answer with the neon_vqrdmulhq_s16 and ssse3_mm_mulhrs_epi16 instructions.
