into account multiplicity, the non-zero rule takes also into account
the orientation of the edge.
This leads to different results as can be seen in the figure below.
For some configurations this leads to different results, as can be seen in the figure below.

A valid polygon with holes, obviously has the same result with both rules applied
as it is just the identity. However an invalid multipolygon with one polygon
enclosing the other one results in a polygon with hole.
enclosing the other one results in the union of the two, that is the enclosing one
for the non-zero rule, while it results in a polygon with hole for the even-odd rule.

Given several valid polygons this rule computes their union or intersection.
This approaches from outside and from inside, respectively.

The conditions listed above are sufficient to define valid polygons, polygons
with holes and multipolygons with holes for most applications. However, in
