One of the reasons that the WebKit codebase is a lot smaller than that of some other browsers is that WebKit takes advantage of frameworks supplied by the operating system when possible. WebKit does not attempt to abstract out all platform differences across the board.
In the case of 3D transforms, WebKit takes advantage of Core Animation on platforms that support it. However, the code is structured in such a way that another platform can substitute its own backend, so there's nothing to stop another port or ports from using clutter.
