Apple's proposals for transforms, transitions and animations have been  
updated today. You can find them at:


The most significant changes are splitting 2d and 3d transforms into  
separate documents and adding a list of properties that can be  
animated (and how to interpolate different property types).

Here is the Changelog.


         * animation-name should accept IDENT not <string>
         * animation-play-state marked as "about to be removed"
         * more description of when an animation is applied, that
           they snapshot keyframes and values as they start and
           how they need to be removed to reset.


         * list of animatable properties and how to animate property
         * specify that values for bezier points outside of [0,1] are


         * split into 2d and 3d specifications
         * transform-origin now matches background-position definition.
         * describe how to animate between lists of transforms


         * new specification which is the 3d parts of transforms
         * perspective must be > 0
         * perspective-origin also matches background-position
         * describe how to animate between lists of transforms, but this
           time in 3d which is harder.

Reviews, comments, etc most welcome.
