Re: float[4][3] into NSValue

If you use NSArchiver/NSUnarchiver then you'll be fine between ppc/
intel.  Unfortunately, as noted in the recent thread "How to archive 
structs like NSRect", NSKeyedArchiver does not support coding of 
NSValues with non-trivial types.  A workaround was also proposed in 
that thread.
