FastTriWinding::ComputeCoeffs

Precompute constant coefficients of triangle winding number approximation P: 'Center' of expansion for Triangles (area-weighted centroid avg) R: max distance from P to Triangles Order1: first-order vector coeff Order2: second-order matrix coeff TriCache: precomputed triangle centroid/normal/area (todo either support passing in as possibly-nullptr or remove commented-out null branches!)
