[geom] Point Inside Polygon - Point on Polygon

[postspectacular]

@dennemark - Looks good & I'm thinking about this, but will have to refamiliarize with the details of that code first (in a different head space right now...)

I am not sure if it is worth implementing this approach within pointInside component. Maybe it can be a separate classifyPolygon function. Since the only reasonable way to get on polygon functionality, is by really checking, if a point is on each line of polygon, therefore creating additional checks within classifyPointPolyPair.

The checks for pt within y range within classifyPointPolyPair vary just slightly ay <= py and by <= py vs ay < py and by < py . The latter is necessary for inside check, the former for on line check.

While this decreases performance for point inside checking, it might actually be bit faster, if point is on polygon, since we can just skip iterating over follow up lines of a polygon.

I have it in my code base now...
