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

The problem is, it doesn't anti-alias, so you have to do some tricks to 
make it work. I believe set ray samples to 1,1 for example, but then of 
course, it doesn't anti-alias. Also rayhittest() doesn't take a spread 
option, so for the blurred reflections, you have to write your own 
spreading. It's not easy :(
