[Insight-developers] image PixelType when using RegistrationMetricv4

[Nicholas Tustison]

Yeah, this is a legacy issue that we need to address but I don't know how 
easy it's going to be.  It's due to the fact that the transform framework requires
double type which predates our work.  Brian, Michael and I will have to 
discuss this to see if we can fix it or at least minimize the places where double
is required.
