* GradientNDAnisotropicDiffusionFunction to pixel types of multiple
* components. Vector components are diffused separately, but diffusion of
* each component is limited by a conductance term which depends on all
* components.
*
* For more information, please see GradientNDAnisotropicDiffusionFunction.
