[vtkusers] Using an ATI Card withe GPUVolumeMapper

[Karthik Krishnan]

Yes. Take a look at vtkSmartVolumeMapper. It has render modes where the
DefaultRenderMode uses the GPUraycaster if its supported, if not uses the 3D
texture mapper and if that's not supported, uses the fixed point software
ray cast mapper.
