As you say float and float1 are two different things in HLSL, but once 
we are deep enough in the pipeline that all the relevant operations 
(like mul()) have been lowered, then we can ignore the difference. As (I 
think) I have said in another email, what I would like to happen is that 
at some point everything is converted to vectors (so we don't have 
scalars lingering around anymore), but it doesn't seem that the others 
agree with me.

Giovanni.
