I'm not fussed one way or the other, but I can see at least two 
advantages in keeping the original code:

1) It's slightly more obvious that the data we are dealing with is four 
bytes of R, G, B and A - although a comment to that effect would be a 
better solution.

2) Compiler optimisers may do a slightly better job on the already 
unrolled loop.

I'll leave it to Alexandre and co. to pick and choose which version 
makes it in.
