Create an empty `PathMeasure` object. To uses this to measure the length of a path, and/or to
find the position and tangent along it, call `PathMeasure.setPath`. Note that once a path is
associated with the measure object, it is undefined if the path is subsequently modified and the
measure object is used. If the path is modified, you must call `PathMeasure.setPath` with the
path.
