Is this in v0.3.1? The documentation for the displace warp indicates
that it takes a pattern rather than a pigment statement. 

If I implemented the method I use in software, rather than using
functions, it would only take eight calls to the crackle function.
Unfortunately, you can't save the return value of a function to use
later, you have to repeat the call and this causes a large processing
overhead.
