Ok, I will. However, while I often sample processes to see what they do, I've 
never thought it could be used to see time consumption.

I'm not sure. With Apple, I've found that as more as a technology is recent, as 
more the result is worse (like graphics antialiasing everywhere and such). I'm 
afraid to change my code only to discover the result is worse.

This time, I'm saving as PNG lossless. I have never compared when I used JPEG 
normal quality (last year). It wasn't on Mac Lion, so comparing is senseless 
anyway.

Indeed, but thanks for having checked.

Thank you.
