[Sidefx-houdini-list] Reflection Blur Based On Distance

It would be interesting if the "Auto-generate Reflection Map" feature 
would allow Deep Rasters to be generated and then queried by the 
environment() call. I believe they are Deep Rasters already (6 sides of 
the cube), so it would be awkward to add arbitrary layers to them (like 
Pz) without a naming-scheme kludge.

I wonder if by any IFD hackery that you can cause these maps to have 
extra layers...
