      boolean onPathForeachFunc(CallbackHandler __self, int op, @Nonnull Point pts, long n_pts, float weight, @Nullable Pointer user_data)
      Type of the callback to iterate through the operations of a path.

      For each operation, the callback is given the @op itself, the points
      that the operation is applied to in @pts, and a @weight for conic
      curves. The @n_pts argument is somewhat redundant, since the number
      of points can be inferred from the operation.

      Each contour of the path starts with a @GSK_PATH_MOVE operation.
      Closed contours end with a @GSK_PATH_CLOSE operation.
      Parameter:
      op - The operation
      pts - The points of the operation
      n_pts - The number of points
      weight - The weight for conic curves, or unused if not a conic curve
      user_data - The user data provided with the function
      Gibt zurück:
      %TRUE to continue iterating the path, %FALSE to immediately abort and not call the function again.
