* do you know the status of "kernels"? Are they used by anything?

* must faces be flat polygons or can they be saddle/pringle shaped?

* must the kernel fall on the face surface or do they float inside a
volume defined by the faces?


I know there is no 3D vector topology in GRASS (yet), but I'd like to
try and be future proof where possible.
