EXIF orientation handling is a ghetto

Hah, this is so true. A few months ago I had to implement the simplest cases for our product (we were receiving pictures from smartphones and sometimes they'd come up rotated.)

Just finding the right documentation on what the tag actually meant was hard enough. Implementing the code - even in Python - was hard: although the implementation itself was trivial, there were some massive gotchas you had to overcome before you could get it working without relying on some image manipulation libraries that have fallen to disuse... in short, a mess.
