title: Can I specify a MongoDB coordinate reference system using the MongoDB Scala driver?
body: <p>I have a MongoDB query using the Scala driver that looks like this:</p>
  
  <pre><code>collection.find(and(geoWithinBox("geometry", swLon, swLat, neLon, neLat),
                     // ...some other conditions...
                 )
  </code></pre>
  
  <p>It turns out that because of information on <a href="https://docs.mongodb.org/v3.0/reference/operator/query/geoWithin/" rel="nofollow">this page</a> regarding Big Polygons, I might want to use:</p>
  
  <pre><code>crs: {
    type: "name",
    properties: { name: "urn:x-mongodb:crs:strictwinding:EPSG:4326" }
  }
  </code></pre>
  
  <p>in the <code>$geometry</code> expression in the JavaScript version of this query, to specify a custom MongoDB coordinate reference system.  Can I do that using the MongoDB Scala driver?</p>
