always compute a cubic tangent
If the inflection of a cubic is also the cusp, the tangent
is degenerate at that t when computed directly. Rather than
giving up, subdivide the curve there and use the computed
control points to compute the tangent.
This strategy also removes the error paths where the tangent
formerly could not be computed.
