smoothstep

smoothstep performs smooth Hermite interpolation between 0 and

1 when edge0 < x < edge1.

This is useful in cases where a threshold function with a smooth transition is desired.

smoothstep is equivalent to:

    genType t;  /* Or genDType t; */
    t = clamp((x - edge0) / (edge1 - edge0), 0.0, 1.0);
    return t * t * (3.0 - 2.0 * t);

Results are undefined if edge0 ≥ edge1.
