OK. Could you create a small function computing the Von Mises stuff, and
call it in both Common/Views.cpp and Graphics/PostElement.cpp? (+ add a
comment saying that this is not a perfect solution...)

I'm not sure either... Adding plugins to perform such treatments is
pretty straightforward, though, so that this might be a good (temporary)
solution--until more general operations on post-processing views are
made available.

That's fine with me.
