Big thanks to dpJudas and Gutawer for helping me with this.

Finally, now you can test and see if a vector is inside the map or in the void. See the example below.

Saved me the trouble of (eventually) getting around to it.

Why is this using an internal function of the node builder?

I didn't know how to use the other versions of the function properly since they involved nodes.

The main issue here is that the semantics of this function are not the same as of P_PointOnSide or P_PointOnDivLineside because it has to consider the special needs of the node builder. Please rewrite this to use P_PointOnDivLineSide. It may need a bit more setup but is the better choice here.
