/**
 * Implementation of FABRIK algorithm, "Forward And Backward Reaching Inverse Kinematics"
 * This implementation deals with a single chain at a time, without support for multiple effectors
 * see "FABRIK: a fast, iterative solver for inverse kinematics"
 * @param {number} size number of points in the chain
 * @param {Float32Array|number[]} positions
 * @param {Float32Array|number[]} lengths
 * @param {number} origin_x
 * @param {number} origin_y
 * @param {number} origin_z
 * @param {number} target_x
 * @param {number} target_y
 * @param {number} target_z
 * @param {number} [max_iterations] More steps will lead to higher accuracy, but at the cost of computation. Generally solution will be reached in just a few iteration so this is just a ceiling
 * @param {number} [distance_tolerance] Minimum squared distance to be achieved to the target, used to terminate earlier before maximum number of iterations is reached
