Redesign vec_bearing to distinguish all directions.

It now returns the shortest representable vector parallel to its
argument, so it can be used to distinguish between all possible
directions of vector.  This means that the rest of the code can be
more flexible it what it produces.  This makes no change to the
resulting font.
