savePathfindPreprocessFor

Saves pathfinding preprocess to persistent storage.

void savePathfindPreprocessFor(const iShape* shape, iOutputStream* os) const;

	shape		The shape for which preprocess should be saved.
	os		An output stream to save the preprocess to.

This obstacle set must have been marked for preprocessing, with the 'markForPreprocessing' creation attribute.

Use this method in conjunction with iObstacleSet::loadPathfindPreprocessFor() to avoid spending time generating preprocess for known obstacle sets.

Preprocess will be updated automatically before saving if not up to date when this method is called.
