Returns a
Geometry that represents the convex hull of this
Geometry.
Convexity requires the use of "lines" or "curves of shortest length" and the use of different
coordinate systems may result in different versions of the convex hull of an object. Each
implementation shall decide on an appropriate solution to this ambiguity. For two reasonable
coordinate systems, a convex hull of an object in one will be very closely approximated by
the transformed image of the convex hull of the same object in the other.
