[vtkusers] Using an ATI Card withe GPUVolumeMapper

[Darshan Pai]

Thanks for the link jerome. I just converted it to a software raycast mapper
and thats runs fine now . I just had another question though. Is it possible
to find out what card we are using in the code and switch mappers between
software and GPU ?
