...I didn't realize what you meant when you said "all messed up":  if  
the colors are weird, it's probably a good indication that channels  
are outta order...I was thinking you meant "messed up" in a deeper  
sense ;-)

...yeh, of course they have they're own (I think they call them  
"flippers"?)...I don't see any reason for us to use them, especially  
since we support ppc and intel cross-platform...so, I think it'd be  
fine to use:

#if defined(__APPLE__) && defined(__LITTLE_ENDIAN__)
or
#if defined(__APPLE__) && defined(__BIG_ENDIAN__)
