Reverse or swap the $(u,v)$ parameterisation of a surface, or flip the normal.

Input parameters:

1. Sf → Surface to reverse.
2. Uu → If true, the U parameterisation is reversed.
3. Vv → If true, the V paramwterisation is reversed.
4. Nr → If true, the normal direction is flipped.
5. Tr → If true, the U and V directions are swapped.

Output parameters:

1. Sf → Surface with reversed parameterisation.
2. Dr → New U (red), V (green) and normal (blue) directions of surface faces.
