Test case: graf08
1. wind forced basin flow (3D, 141x47x45 grid, 20 time steps)
2. wind forced basin flow (3D, 141x47x45 grid, 20 time steps)
3. vector field * wind forced basin flow (3D, 141x47x45 grid, 20 time steps)
4. basin LIC visualization
5. basin LIC animation

Test case: graf04
1. wind forced basin flow (3D, 141x47x45 grid, 20 time steps)
2. idem, volume visualization based on ff2 value

compare test cases graf04 and graf08
