/**
 * Implementation of the string-pulling algorithm for funnel path refinement.
 * Does not allocate memory.
 *
 *
 * @param {Uint32Array|number[]|ArrayLike<number>} output Indices of vertices are written here
 * @param {number} output_offset where to start writing into the output, typically you want to pass 0 here.
 * @param {Uint32Array|Uint16Array|Uint8Array|number[]} portal_vertices Flat array of vertex index pairs [left0,right0, left1, right1 ... leftN, rightN]
 * @param {Float32Array|number[]|ArrayLike<number>} portal_normals Normal vectors for each portal. Should be set to the triangle normal, which we exit through this portal. can be filled with [up, up, up... ] if your portals lay in the horizontal plane mostly.
 * @param {number} portal_count how many portals do we have to work with
 * @param {Float32Array|number[]} vertex_data actual vertex positions
 * @returns number of vertices written to the output
