In this case, the argument is being used as an output, not as an input.
I'm not sure why ITK would want to take this approach.  In my mind, it's
*always* better to return values as retvals, rather than through "inout"
arguments if at all possible.  On the other hand, I'm probably the
*last* person anyone should consult on the subtleties of ITK
architecture.
