// 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,

// 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].
//
// Arguments:
// path = the path to process. A list of 2d points.
// r = offset radius. Distance to offset. Will round over corners.
