(

PK_FACE_t        face,      --- Face to contain new loop

--- returned arguments ---
PK_LOOP_t *const new_loop   --- One of the two loops created
)


This function adds a new loop to a face.


This function adds two new loops on either side of a single ring edge to a
face.  The 'new_loop' returned lies to the right of the new edge.

There will be no geometry attached to the new edge so the resulting body will
be invalid.

The inverse of this function is PK_EDGE_euler_delete_ring_loop
