Remarks

Moves from the start to the end position constrained to the navigation mesh.

This method is optimized for small delta movement and a small number of polygons. If used for too great a distance, the result set will form an incomplete path.

resultPos_ will equal the endPos_ if the end is reached. Otherwise the closest reachable position will be returned.

`resultPos_ is not projected onto the surface of the navigation mesh. Use getPolyHeight if this is needed.

This method treats the end position in the same manner as the raycast method. (As a 2D point.) See that method's documentation for details.

If the `visited_ array is too small to hold the entire result set, it will be filled as far as possible from the start position toward the end position. The status flags for the query.
