   * Paths

   * We are using the 'noop' method of a path here, which is pretty low-level freesewing stuff
   * By passing the noop method with an ID, we are merely marking this among the different path
   * (drawing operations). This allows us to easily inject operations at this point later,
   * which is exactly what the insertDraft() method does.
   * Doing this allows us to use the same base path for both the seam line and SA outline
