[vtkusers] Can any body help!

[Amy Squillacote]

Is there a particular reason you have to use vtkVolumeRayCastMapper? If 
not, try using vtkFixedPointVolumeRayCastMapper; it can handle any 
scalar type.

If you need to use vtkVolumeRayCastMapper, pass your data through 
vtkImageShiftScale to convert it from short to either unsigned short or 
unsigned char, and then pass the output of the vtkImageShiftScale filter 
to vtkVolumeRayCastMapper.
