- * The vert[] array lists vertices, indexed by binary order of initial axes,
- * where X has weight 1, Y weight 2, Z weight 4.
- * Initially "min" corresponds to 0, "max" to 1.
- * Specifically GeomCreate("bbox", CR_MIN, min, CR_MAX, max) makes a bbox with:
- * vert[0] = (min.x, min.y, min.z)
- * vert[1] = (max.x, min.y, min.z)
- * vert[2] = (min.x, max.y, min.z) ...
- * vert[7] = (max.x, max.y, max.z).
- * Note this property isn't necessarily preserved if the bbox is transformed.
