NAME
SortByZ - Returns a geom as a polylist with its polygons in increasing
order by z value.
SYNOPSIS
Geom *SortByZ(Geom *);
DESCRIPTION
SortByZ() takes a geom as its argument. The geom is first converted
to a polylist (See anytooff(3)). The polygons of the new polylist
are sorted into increasing order by their lowest z value. If the
lowest z values of the points of two polygons are equal, the highest
z values are compared. SortByZ() then returns the new polylist.
BUGS
SortByZ() calls AnyToOff() and so has all the same bugs.
