I understand that you may be feeling "got at" here, but to be fair the OP does have a point in that the code definitely does suffer from a distinct paucity of comments - and while you say the libraw focus is on extracting data from raw files, there's still a very high proportion of the code dedicated to post-processing the raw image.
I truly don't expect you to drop everything and add reams of comments but if the next time you go near any code that lacks comments, adding some lines to explain how/why it's doing what it does would be most helpful to the rest of us.
