You are correct. It appears that when I draw the text with
foreground alpha it is honored so only the background alpha is
ignored. Strange... would anyone else consider this to be either a
documentation or an API bug? Maybe I'm missing something, but it
seems like the behavior should be consistent.
Well, I'd have expected the background to be filled using the
CompositeAtop mode or so as well, but at the least I would have
expected a mention of the background being painted in copy mode.
Definitely a bug either way. I hope nobody relies on the "copy"
behaviour yet, that so Apple still dares fixing the behaviour to be
consistent with the foreground color. I'd definitely recommend that
everything who's encountered this bug file a bug report at http://
bugreport.apple.com.
