The first three columns are the the direction cosine vectors (for these,
the 4th component should be zero).  The three direction cosine vectors
should be perpendicular to each other.

The fourth column (whose 4th component must be 1.0) gives a translation,
defined with respect to the coordinate system of the input of
vtkImageReslice.
