Agreed, however I leave that part up to the user, as this just corrodes 
whatever you tell it to.
I was trying to use some sort of crackle around the edges of the corrosion, 
but that didn't work.
I guess I could scale the main blob used to do the corroding, but would that 
not be unpredictable and invoke more of a memory overhead than is needed?
