Michael, I'm sorry. I just realized I hadn't replied to you yet; sorry for the delay. John also pointed us to the transforms branch and that's where we'll start. Thanks! There's no real advantage to CoreAnimation per se (except eye candy), but going "native" for rendering would allow mpl to integrate more smoothly with the rest of the 2D and 3D (much of Quartz, and CoreImage the 2D rendering and filtering systems in OS X are actually rendered on the graphics card as OpenGL) rendering system in OS X. Some advantages, off the top of my head are resolution independence, ability to offload rendering and/or coordinate transformation to the graphics card, ability to easily produce output in any of the CoreImage supported formats, ability to incorporate transparency and alpha blending within the view hierarchy, ability to combine media (QuickTime, OpenGL, and Quartz) in layers (the real purpose of the CoreAnimation engine), ability to piggy back on improvements in Apple's rendering engine (things like anti-aliasing etc.), ColorSync support, and _maybe_ some speed improvements by taking a layer or two out of the rendering process. All of these are just speculation, at this time... we're just getting started but will share our results as soon as they're ready.
