This path effect chops a path into discrete segments, and randomly displaces them.

away from the original path by a maximum of deviation.
Note: works on filled or framed paths
@param seedAssist This is a caller-supplied seedAssist that modifies
the seed value that is used to randomize the path
segments' endpoints. If not supplied it defaults to 0,
in which case filtering a path multiple times will
result in the same set of segments (this is useful for
testing). If a caller does not want this behaviour
they can pass in a different seedAssist to get a
different set of path segments.
