No, not a big problem, I just wanted to make sure it was required. I'm not yet 
very deep (excuse the pun) in the "comp" part of deep comp -- I've written the 
renderer part, and know it's outputting sorted, non-overlapping samples, and as 
I write various reading software, I'm just trying to make sure that the added 
complexity of handling messy files (which I'm not generating) has a 
justification.
