	Returns the tangents for the given face.

Detailed Description

Tangents along a face in winding order.

Construct once and call per face.

e.g. geo::FaceTangents faceTangents(mesh, TangentMode::TwoPoint); for (Offset face : mesh.getFaces()) for (Vector3 tangent : faceTangents(face)) ...

Note: Each call replaces the previous result, so finish reading a face's tangents before asking for the next.
