path node culling

[Derision]

The culling is there to optimize the path.

Without culling you can get situations were the nearest node to the destination (e.g. to the player who a mob has aggroed on) will cause the aggroed mob to run past the player to that last path node, then run back to the player.

Similar issues can occur at the start of a path without culling, i.e. a mob runs away from it's target to the nearest path node before beginning to traverse the node path.

The culling was an attempt to stop that happening.

Thanks for the clarification.

The culling is working fine, and is not related to what I was seeing.
But anything unexpected becomes suspect.

That particular problem was due to pathing going underground after
the last node was reached. Nothing to do with path nodes. FindBestZ
"corrected" the destination Z to deep underground. I changed the code
to use FindClosestZ, and the pathing was correct.

I'm not ready to recommend that change in general. I need to study a variety of scenarios before I'm confident that I understand what is happening.
