     * kring;
     * >but most datasets are set up with Cesium's default of 16 in mind so they'll look good with that default
     * >SSE is a projection of the tile's "geometric error" (in meters) to the screen. What effect that has kinda depends on how the tileset is structured
     * >like for the aero3Dpro datasets, because of the way they've set up their levels and geometric error, 16 looks pretty terrible
     * >and if you set it to 1 instead you'd get like 16 * 16 more detail and probably crash the browser
     * >(it's squared for 2D, more like cubed for something that's truly 3D)
