New description:

 * ~~We need to apply a buffer on the MVT tile region so that client
 applications can properly stitch together features that cross tile
 boundaries~~
  * ~~Multi-polygons that cross tile boundaries are not being rendered
 Multi-geometries are not supported in the vector tile spec (see:
 [https://github.com/mapbox/vector-tile-spec/tree/master/2.1#434-geometry-
 types 4.3.4 Geometry Types]), so such multi-geometries should be exploded
 into its constituent geometries~~
  * ~~Geometries should be simplified at higher levels~~
  * Certain geometries near tile boundaries are not rendering at certain
 levels. Examples include:
    * China from the
