Apple Confirms Resolution Independence in Leopard Through WWDC Email
Quote from email;
"For Alykhan [example developer], that means he'll come away with the knowledge he needs to use Quartz and Cocoa to make his products completely resolution independent."
This isn't news. Apple confirmed to Developers that this would be in Leopard more or less when Tiger shipped. It's actually in Tiger, just not at the user level as it's a bit buggy and not all apps work properly with it.
Hmm, at WWDC 2006 I'm pretty sure they said it'd be two years away. Of course, they can put it in Leopard now (they have!) then add hardware support later (ie. higher-density displays).
The last WWDC presentations said that the developers should be ready by 2008. I don't know what's coming in 2008, but I suppose its something with oddball resolutions. Maybe Hi-Res screens or iPhone developers kits?
