> (1) CATextLayer in iOS 6 requires an opaque background in order to antialias text. CATextLayer in iOS 5 did not have this limitation; it could antialias its text perfectly well even if its background was transparent. Why the change? I'm guessing that it's an efficiency boost.

I may be confused about this one. I was put off by the fact that my text looks awful on the full-sized Retina simulator, but now it appears that it *always* looked awful on the full-sized Retina simulator. It seems that CATextLayer is **drawing** the text, not using the text system. So now I have a different problem, namely that I don't understand the note at the top of the CATextLayer class docs, since my text drawing in CATextLayer looks the same with or without an opaque background. m.
