+ @param shape The shape of the geographic region to be covered by
+    the downloaded tiles.
+ @param minimumZoomLevel The minimum zoom level to be covered by the downloaded
+    tiles. This parameter should be set to at least 0 but no greater than the
+    value of the `maximumZoomLevel` parameter. For each required tile source, if
+    this parameter is set to a value less than the tile source’s minimum zoom
+    level, the download covers zoom levels down to the tile source’s minimum
+    zoom level.

+    `minimumZoomLevel` parameter. For each required tile source, if this
