[vtkusers] Question with vtkImageViewer2

[Ken Urish]

For the class vtkImageViewer2, is there any logic why it only works
with greyscale unsigned char pixel types??? I want to extend its
functionality to rgb signed short. I know this is a wrapper class, and
Im trying to see how difficult it will be to change the code myself to
add this functionality. This is the first time I am tweaking vtk
source code so I am trying to triage any unexpected problems.

Thanks
