[Insight-developers] ITK_EXPLICIT_INSTANTIATION breaks Insight Test build in Insight/Code/Common/itkPhasedArray3DSpecialCoordinatesImage.h?

[Kent Williams]

There is code in itkPhasedArray3DSpecialCoordinatesImage.h that is 
broken if ITK_EXPLICIT_INSTANTIATION is defined.

#ifdef ITK_EXPLICIT_INSTANTIATION
   extern template class 
PhasedArray3DSpecialCoordinatesImage<float         ,2>;
   extern template class 
PhasedArray3DSpecialCoordinatesImage<double        ,2>;

etc.

The problem is that PhasedArray3DSpecialCoordinateImage<> now supports 
only 3D, and has only one
template parameter.

It looks like eliminating the 2D explicit instantiations, and fixing the 
3D cases allows compilation to complete. My question is should I just 
check in this change, or does someone who actually knows this code want 
to take a look?
