The result is a planar WGS84 rectangle.
If (east - west) ≥ 360 then the longitude range will be normalized to -180 to
+180; otherwise they will be treated as designating points on a circle (e.g. east may be numerically less than west).
|Number||The westernmost enclosed longitude. Will be adjusted to lie in the range -180° to 180°.|
|Number||The southernmost enclosed latitude. If less than -90° (south pole), will be treated as -90°.|
|Number||The easternmost enclosed longitude.|
|Number||The northernmost enclosed longitude. If greater than +90° (north pole), will be treated as +90°.|
