Constructs a rectangle whose edges are lines of latitude and longitude.
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).
The westernmost enclosed longitude. Will be adjusted to lie in the range -180° to 180°.
The southernmost enclosed latitude. If less than -90°
(south pole), will be treated as -90°.
The easternmost enclosed longitude.
The northernmost enclosed longitude. If greater than
+90° (north pole), will be treated as +90°.
