Bartosz Kosiorek 1e5ede1942 Physics: Increase precision of 4D vector normalization functions 
More accurately normalize 4D vectors, to avoid potential
numerical stability issues in Mantaflow.

For consistency with changes from #136966.

Mantaflow

Mantaflow is an open-source framework targeted at fluid simulation research in Computer Graphics. Its parallelized C++ solver core, python scene definition interface and plugin system allow for quickly prototyping and testing new algorithms.

In addition, it provides a toolbox of examples for deep learning experiments with fluids. E.g., it contains examples how to build convolutional neural network setups in conjunction with the tensorflow framework.

For more information on how to install, run and code with Mantaflow, please head over to our home page at http://mantaflow.com

Debugging

You could export openVDB volume into mantaflow, by running Blender with:

blender --debug-value 3001

And then select Domain -> Fluid -> Cache - > Advanced -> Export Mantaflow Script.
