// GeometryFacade in GeometryFacade, and one to ExternalGeometryFacade. I have not managed to find a

// Summary Remarks:
|
|
// It is intended to have a separate type (not being a Geometry type).
|
|
// it is intended to have the relevant interface in full for the sketcher extension only
|
|
// It is intended to work on borrowed memory allocation.
