pub const NEAREST_HANDOFF: f64 = 1e-3;Expand description
Where a nearest-point search hands over to Newton, as a fraction of the
size of what it searches (NurbCurve::closest_point,
NurbSurface::closest_point). Bounds effort only: every piece left at
the handoff that could hold a nearer point is refined, so a coarser
handoff only leaves Newton more pieces to start from.
