How do you determine containership?
Tanks in advance

The answer was enlightening, though I'd have to do a lot more thinking about
why it doesn't matter, if some polygons are intersecting.
If a polygone is complex, i.e. has holes, the cast ray will pass an odd
number
of edges, if the start point is inside the polygon. Numerically
