<p>The center method calculates the center of a bbox and returns it as a GeoJSON position.</p>
<p>It operates on bounding boxes and should not be confused with the centroid function, which operates on GeoJSON geometry objects.</p>
<p>This function is called Envelope.centre in JTS (I assume because JTS is built in British Columbia).</p>
