I was suggesting a short-term fix just to provide this support, but I'm 
not sure why... as you say, it won't be faster (although I guess it 
could take advantage of being able to perform multiple simultaneous FFTs).

Since we don't need these right away and can always put them back later, 
should I rip the r->c and c->r support out for now, just to avoid 
confusion?
