+## split
+reproject-bbox will automatically split bounding boxes where x=0 and y=0 before reprojecting and merging them back together.  This can greatly improve accuracy for certain projections, especially ones around the poles.  However, if you really want to turn it off, you can.
+```js
+reprojectBoundingBox({
+  bbox,
+  from: 3857,
+  split: false, // turn off automatic splitting
