I just finished adding turbulence to the glow patch, it seems to work 
pretty well. Here are some of my experiments with it:
Lamda, omega, and octaves were left at their defaults.
turbulence1.jpg has a turbulence amount of 10 and turbulence scale of 1.
turbulence2.jpg: amount 0.35, scale 0.1
turbulence3.jpg: amount 0.5, scale 1
I am still working on making the turbulence scale feature work with 
patterns and ordinary warps as well as with glow. The current syntax 
just adds an optional vector parameter following the existing "amount" 
parameter.
