 // Description:
-//   Takes an input path and returns a path offset by the specified amount.  As with the built-in offset() module, you can use
-//   `r` to specify rounded offset and `delta` to specify offset with corners.  Positive offsets shift the path
-//   to the left (relative to the direction of the path).

-//   When offsets shrink the path, segments cross and become invalid.  By default `offset()` checks for this situation.
-//   To test validity the code checks that segments have distance larger than (r or delta) from the input path.
-//   This check takes O(N^2) time and may mistakenly eliminate segments you wanted included in various situations,
-//   so you can disable it if you wish by setting check_valid=false.  Another situation is that the test is not
-//   sufficiently thorough and some segments persist that should be eliminated.  In this case, increase `quality`
-//   to 2 or 3.  (This increases the number of samples on the segment that are checked.)  Run time will increase.
-//   In some situations you may be able to decrease run time by setting quality to 0, which causes only segment
-//   ends to be checked.

-//   For construction of polyhedra `offset()` can also return face lists.  These list faces between the
-//   original path and the offset path where the vertices are ordered with the original path first,
-//   starting at `firstface_index` and the offset path vertices appearing afterwords.  The direction
-//   of the faces can be flipped using `flip_faces`.  When you request faces the return value
-//   is a list: [offset_path, face_list].
