[vtkusers] Mappers and vtkLookupTable

We are trying to render geometry using a lookup table for the RGB value using one scalar variable, but we want to use a secondary scalar variable for determining the opacity.  Something like the following:

RGB -> variable one
A -> variable two

In looking through the VTK 6 documentation on mappers we have not found anything that leads us to believe this functionality is possible. But we have done an exhaustive search.

If it is possible we would greatly appreciate pointers. Thanks.
