App::MathImage::LinesLevel -- replication level line drawing
This is a special kind of "values" which draws lines between the points of the path through to a selectable replication level, holding the endpoints fixed.
This is designed for paths like the KochCurve or Flowsnake where the replication levels turn each line segment into a further shape.
The current code depends on some hard coded setups for the levels of the various paths, and doesn't work well at all on non-replicating paths.
