Tie lifetime of SVGAnimateElement::m_animatedType to the duration of the animation. For non-frozen animations, we still keep the animVal around and just reset it to the base val. For CSS property animations we never remove a property if we animated it via SMIL, but only change it back to the base value. This makes integration with CSS Animations/Transitions hard, and needs to be changed both for CSS & XML animations. Unfortunately that requires a precise knowledge of which animation is contributing to an animated value at any point in time. Patch upcoming.
