Use new offset capabilities to add a hole to a closed path with unifo…

…rm thickness from the perimeter (#685)

* Extrude can send IDs for the new faces

When extruding a 2D shape into a 3D shape, a bunch of new faces are created.
These faces need IDs. The backend currently generates these IDs randomly.
Add a new option to allow the client to send the IDs.

* AddHoleFromOffset
