[Insight-developers] ITK_USE_TEMPLATE_META_PROGRAMMING_LOOP_UNROLLING in ITKv4

[Luis Ibanez]

Hi Hans,

Thanks for taking care of this one.

Removing was the right way to go.

At some point, it will be interesting to revisit the template
metaprogramming that was used to implement the matrix
multiplications, and see if we can write it better, now that
we can use partial specialization.


     Luis
