 * Terrain data for a single tile where the terrain data is represented as a quantized mesh.  A quantized
 * mesh consists of three vertex attributes, longitude, latitude, and height.  All attributes are expressed
 * as 16-bit values in the range 0 to 32767.  Longitude and latitude are zero at the southwest corner
 * of the tile and 32767 at the northeast corner.  Height is zero at the minimum height in the tile
 * and 32767 at the maximum height in the tile.

     * @property [quantizedVertices] The buffer containing the quantized mesh.
     * @property [indices] The indices specifying how the quantized vertices are linked
     *   together into triangles.  Each three indices specifies one triangle.
     * @property [minimumHeight] The minimum terrain height within the tile, in meters above the ellipsoid.
     * @property [maximumHeight] The maximum terrain height within the tile, in meters above the ellipsoid.
     * @property [boundingSphere] A sphere bounding all of the vertices in the mesh.
     * @property [orientedBoundingBox] An OrientedBoundingBox bounding all of the vertices in the mesh.
     * @property [horizonOcclusionPoint] The horizon occlusion point of the mesh.  If this point
     *   is below the horizon, the entire tile is assumed to be below the horizon as well.
     *   The point is expressed in ellipsoid-scaled coordinates.
     * @property [westIndices] The indices of the vertices on the western edge of the tile.
     * @property [southIndices] The indices of the vertices on the southern edge of the tile.
     * @property [eastIndices] The indices of the vertices on the eastern edge of the tile.
     * @property [northIndices] The indices of the vertices on the northern edge of the tile.
     * @property [westSkirtHeight] The height of the skirt to add on the western edge of the tile.
     * @property [southSkirtHeight] The height of the skirt to add on the southern edge of the tile.
     * @property [eastSkirtHeight] The height of the skirt to add on the eastern edge of the tile.
     * @property [northSkirtHeight] The height of the skirt to add on the northern edge of the tile.
     * @property [childTileMask] A bit mask indicating which of this tile's four children exist.
     *   If a child's bit is set, geometry will be requested for that tile as well when it
     *   is needed.  If the bit is cleared, the child tile is not requested and geometry is
     *   instead upsampled from the parent.
     *   Default value - `15`
     * @property [createdByUpsampling] True if this instance was created by upsampling another instance;
     *   otherwise, false.
     *   Default value - `false`
     * @property [encodedNormals] The buffer containing per vertex normals, encoded using 'oct' encoding
     * @property [waterMask] The buffer containing the watermask.
     * @property [credits] Array of credits for this tile.
