old 2-halves in one patch:
- face ordering after topological changes becomes much easier since we Advantages:
now preserve what half the face comes from.
- cyclic handling becomes more consistent with processor handling and can
quite often be handled in the same condition.
- decomposed cyclics can now be handled properly. It just needs to preserve - decomposed cyclics can now be handled properly. It just needs to preserve

- transformation tensors now become single entry.
The disadvantages: The disadvantages:
- a patch-wise loop now might need to store data to go to the neighbour half - a patch-wise loop now might need to store data to go to the neighbour half
