Improve FP-precision by setting wavefront amplitude as opposed to scaling output PSFs?

[LouisDesdoigts]

If wavefront amplitudes are set upstream before the propagation, then the necessarily small values output by unitary PSFs can be avoided. This should help alleviate FP precision issues, but is likely difficult to implement since the Wavefront can be normalized at any point during the transformations. Ideally this would be done before each propagation.
