I just imagine this going really wrong. My chain of thought would be something like: "Let's see, I need to rotate this image so I need to loop over rows then columns, .. gawd fuck this code base is shit designed, there are no units on these fields, this could be so much cleaner, ... for each row ... I wonder what's for lunch today? I hope it's good ... for each column ... Dang that response on HN really pissed me off, I'd better go check it ... read pixel from source ... tonight I meeting up with a friend, I'd better remember to confirm, ... write pixel to dest ...."
