			This partially implements CSS-Animations-1 (though there are references to CSS-Animations-2). Current limitations: - Multi-selector keyframes are not supported. - Most animation properties are ignored. - Timing functions are not applied. - Non-absolute values are not interpolated unless the target is also of the same non-absolute type (e.g. 10% -> 25%, but not 10% -> 20px). - The JavaScript interface is left as an exercise for the next poor soul looking at this code. With those said, this commit implements: - Interpolation for most common types - Proper keyframe resolution (including the synthetic from-keyframe containing the initial state) - Properly driven animations, and proper style invalidation Co-Authored-By: Andreas Kling <kling@serenityos.org>
