[Insight-developers] removing transforms from Image

[Damion Shelton]

The removal of the transforms from itk::Image is going smoothly with 
(so far) two exceptions. The first is itkAffineTransform test, which 
also tested the ability to retrieve the default affine transform from 
itk::Image. I removed this part of the test, since it no longer applies.

The second problem is in itkImageMomentsCalculator.txx - it looks like 
the conversion between index and physical space is being done manually 
by retrieving the stored transform on line 79 and using it on line 118. 
If this is all that's happening, the same functionality can be achieved 
by calling:

image->TransformIndexToPhysicalPoint( indexPosition, physicalPosition);

in line 118.

Can someone verify that this is the correct solution? I have not yet 
checked in any of these changes.

Thanks,
