[vtkusers] multiple volume rendering

[Lisa Avila]

Hello Radu,

Do your two volumes overlap? If not, you can simply create two volumes, two 
volume mappers, two functions, etc. and add them both to the renderer. Make 
sure to get the Culler from the renderer and turn on back to front sorting 
of the props so the volumes will composite in the correct order.
