[vtkusers] RayCasting through two datasets

[Benjamin King]

Hi Martin,

let's say the maximum of the first dataset is less than m. Then you could 
add m to all non-zero values of the second dataset and finally add the two 
datasets. Then the part of the transfer function below m is for the first 
dataset and the part above m for the second.

Best regards,
   Benjamin
