   * For remapping texture coordinates when rendering GroundPrimitives with materials.
   * GroundPrimitive texture coordinates are computed to align with the cartographic coordinate system on the globe.

   * using different strategies.
   *
   * This method is used by EllipseGeometry and PolygonGeometry to approximate the same visual effect.
   * We encapsulate rotation and scale by computing a "transformed" texture coordinate system and computing
   * a set of reference points from which "cartographic" texture coordinates can be remapped to the "transformed"
   * system using distances to lines in 2D.
   *
   * This approximation becomes less accurate as the covered area increases, especially for GroundPrimitives near the poles,
   * but is generally reasonable for polygons and ellipses around the size of USA states.
   *
   * RectangleGeometry has its own version of this method that computes remapping coordinates using cartographic space
   * as an intermediary instead of local ENU, which is more accurate for large-area rectangles.
