static DualMidpointSmoother smoothChaikinToMinArea(double minArea) {
    return DualMidpointSmoother.chaikinToMinArea(minArea);
  }
Returns a new smoother that slices off each corner, except instead of stopping at a fixed number of iterations, it
stops when the area formed between a vertex and its 2 adjacent neighbors is below {@code minArea}.
