I realized there's a logical fallacy to my above statement. Not only
the continuous parts, but also the straight lines need to be evaluated
as part of the path, because the curves (barring {dir} or explicit
control specifications) will try to be as smoothly connecting to the
straight lines as possible. So it is necessary to know the straight
line segments also to determine the appropriate smoothening control
points for the curved segments.
