// the face lookup needs to be done based on the rotation. Thus, for a samm

// cell, firts find out the face index in the normal rotation using the cell
|
|
// face permutation table and then use the index from the shape face lookup.

// Additionally, have in mind that this silliness does not allow matches

// on face 7 and 8 of the samm cell.
