 * Simplifies given 2D shape boundary using Douglas-Peucker algorithm
 * (implemented by
 * [`simplify`](https://docs.thi.ng/umbrella/geom-resample/functions/simplify.html))
 * and given `threshold` distance (default: 1e-6, which removes only co-linear
 * vertices).
 *
 * @remarks
 * Currently only implemented for:
 *
 * - {@link ComplexPolygon}
 * - {@link Path}
 * - {@link Polygon}
 * - {@link Polyline}
 *
 * Use {@link asPath}, {@link asPolygon} or {@link asPolyline} to convert other
 * shape types first.
