The edges look sort of beveled--is that deliberate, or just my eyes playing tricks with the contrast?

Deliberate; a subtle effect with a fuzzy border and a gradient.

I hope you get some rest tonight.

Problem is, I'm seeing "The Curse of the Were-Rabbit" tonight, and I don't know how late I'm going to be getting home. I am right now fuelling up on iced coffee in the hope that it will help me not doze through the movie.
