code: @Deprecated
      public GeographyPointValue scale(GeographyPointValue center, double alpha) {
          return GeographyPointValue.normalizeLngLat(alpha*(getLongitude()-center.getLongitude()) + center.getLongitude(),
                                                     alpha*(getLatitude()-center.getLatitude()) + center.getLatitude());
      }
docs: Return <code>alpha*(this - center) + center</code>.  This is
  used to scale the vector from center to this as an offset by
  alpha.  This is equivalent to <code>this.sub(center).mul(alpha).add(center)</code>,
  but with fewer object creations.
  
  @param center The origin of scaling.
  @param alpha The scale factor.
  @return The scaled point.
