I agree with ChrisPlatt that it's really not a nice term, not very politically-correct to say the least.
I don't know where the name 'DX' coding on film cans came from: when it appeared, it was just another thing we didn't need that someone put an X on to make it sound cool.
I'm pretty sure that the idea of a 'Judas window' has centuries-old origins in some Christian story (Possibly even an apocryphal one from popular 'passion play' stories with origins in the Dark Ages: remember, books were precious, in another language, and people couldn't/weren't *allowed* to read that Bible, and things came second, third, or fourth-hand. Was, at least, an occasional painting trope: I remember from art history it was at least used as such. Which came first, is anyone's guess at this point.
I'm gonna lean toward it not being about Renaissance art history, but rather orally-passed stories, just on grounds it doesn't actually seem to appear so often, so it's more likely such paintings came from the folk-tale/turn of phrase, rather than the other way around.
I also have no idea what's supposed to be 'un-PC' about it. But the only people who say 'un-PC' (like that means anything coherent) are kind of manufacturing 'enemies' of anything remotely related to their religion, anyway. 'Judas' was the sneaky bad guy, sneaky bad guys might use peepholes, (More like sneaky bad guys might be called 'Judases' to be more precise) ... nuff said, probably.
