My life is an episode of Monk

I just copied a pair of 18th Century scientific illustrations and, looking at them, thought "My God, these things are crooked! I cannot use them like this." So I opened them each in a cheap graphics program and grabbed the rotate tool where I discovered the first illustration was one whole degree out of alignment. Clearly, the OCD meds are not working as well as they used to. Worse, the second illustration was one and a half degrees out of alignment and the cheap tool I was using could only make full degree adjustments. If I wasn't so poor, that half degree would be enough to drive me to get a full-fledged graphics program.
