I believe the original logic to this was that the typical minc file output of
minctracc is a non-linear grid.

The processing variable contained the contents of the linear affine xfm that was
part of this (non-linear) transformation.  I guess louis the plan here was that
if the linear and non-linear part of a xfm got split up, then all you needed was
the non-linear part to re-create the whole (admittedly, manually).

Well, it never was part of any specification that I can remember. Any
programmer/user is always going to be free to put any variable they like into
the header and even more so in MINC 2.0!
