Abstract the next function, computeRowFromOffset(), out of the individual Movement classes.
Still two issues:
1) mysterious 1.5 multiplier in Movement12
2) in Movement8, moving the offset works only if the rotAxis are face-turning, i.e. they connect the centers of the opposing faces of the octahedron.
