The direction of a trace through a sample point is undefined.  You only have
a discrete sequence of Cartesian samples.

Better to describe traces with 'width' data as the envelope of a sequence
of circular dots of diameter given by the 'width' data.  The trace generated
by a circular brush of varying diameter.
