I've searched the forums, Apple's website, and the web in general and no one seems to be able to give a definitive answer. In Leopard, when you zoom in on the screen (ctrl+scroll or Universal Access) does this take advantage of the resolution independence frameworks? i.e. When you zoom, is the text still crisp, or does it get all jaggy? Please only respond if you have Leopard 9a466 from WWDC 2007 installed, and know for sure. Until this is answered by someone, don't respond that you also want to know, don't respond that you would like this feature, don't respond that you think that there is no good way to implement this feature. Unless you can give definitive proof that it is either smooth and crisp, or jagged like 10.4 and earlier, just wait until someone who knows answers before replying.
