# Wang's bound: a cubic cut into n equal parameter steps stays within e of
# its chords when n >= sqrt(3/4 * L / e), L the larger second difference of
# the control points. The bound assumes the curvature all sits in one place,
# so the tolerance is doubled to land near the adaptive count; the count is
# fixed up front and each point costs one evaluation and no flatness test.
