/**
 * Given a grid of passable/impassable navcells (based on some passability mask),
 * computes a new grid where a navcell is impassable (per that mask) if
 * it is <=clearance navcells away from an impassable navcell in the original grid.
 * The results are ORed onto the original grid.
 *
 * This is used for adding clearance onto terrain-based navcell passability.
 *
 * TODO PATHFINDER: might be nicer to get rounded corners by measuring clearances as
 * Euclidean distances; currently it effectively does dist=max(dx,dy) instead.
 * This would only really be a problem for big clearances.
