that they participate in mutual fill rule calculations like
the polygons inside a single poly-polygon do. When rendering
such a poly-polygon without transparency, it will look like the
constituting poly-polygons rendered separately on top of
another. Alas, when rendering with transparency, separate
rendering will combine the alpha of overlapping areas, whereas
addPolyPolygon results in constant alpha, regardless how many
internal poly-polygons overlap at a single place.

upper, left edge of the referenced poly-polygon will be at
this position relative to the target poly-polygon.
@param polyPolygon
The poly-polygon to add. Note that the content of this
poly-polygon is copied, later changes to polyPolygon will have
no effect on the poly-polygon it was added to.
