Changing the scale of the cells in the crackle pattern would be 
something to do internally in the pattern (and it would no more allow 
the current speedup techniques probably).

Changing the scale of any pattern locally is nothing more than a 
non-linear transform of the coordinates which is already possible at the 
moment.  A function warp would just simplify this a bit.
