I've now added f_spotted and the problem is completely fixed (plus it now 
looks like an even more dramatic ocean!).

The foam is controlled using a nearly identical version of the f_ridged_mf 
that defines the surface, but with the gain parameter cranked up a bit so it 
picks up the higher frequencies more to make a more interesting shape. 
That's averaged with a crackle form <1,0,0> pattern to look a bit like some 
bubbles.
