Firefox for Mac to move away from QuickDraw
This doesn't come as a big surprise but anyways:
On the Mac side of things, Goodger said Firefox 1.0 uses Apple's QuickDraw technology to draw to the screen, while the Windows version uses GDI. However, he said the next big move for the Mac version of Firefox would be away from QuickDraw. QuickDraw, which Apple created in 1984, was the basis for 2D screen presentation in the Mac OS. With the advent of Mac OS X, Apple moved away from QuickDraw to its PDF-based Quartz rendering system, which is now incorporated in the Core Graphics architecture of Mac OS X.
