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.
