[Corona-users] Re: corona flip? texcoords differ between corona, Max/Cal3d

I'll go ahead and make FlipImage operate in-place.  Are you using Corona on a 
console or with a custom memory manager?  If so, I'd be interested to hear about it.

About iterators...  the idea seems good to me, but it would take a little 
planning.  For now, I think doing standard row swaps is fine.
