> LUCENE-8496 allows for selecting the first n dimensions to be used for building the index and the remaining dimensions to be used as data dimensions. This feature changes {{LatLonShape}} encoding to a 7 dimension encoding instead of 6; where the first 4 are index dimensions defining the bounding box of the {{LatLonShape.Triangle}} and the remaining 3 data dimensions defining the vertices of the triangle.
