I don't think this is a very useful interpretation of a function as a 
warp, even if it leads to interesting results in this case.  The pattern 
gets scaled by the value of the function - to imagine how this 
influences a pattern seems quite difficult to me.

I think the most intuitive interpretation of a float function as a warp 
would be the gradient - like it is used in the type 1 displace warp.
