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).
|Float||The westernmost enclosed longitude. Will be adjusted to lie in the range -180 to 180.|
|Float||The southernmost enclosed latitude. If less than -90 (south pole), will be treated as -90.|
|Float||The easternmost enclosed longitude.|
|Float||The northernmost enclosed longitude. If greater than +90 (north pole), will be treated as +90.|
