19.3 Animation using the SVG DOM
If scripts are modifying the same attributes or properties that are being
animated by SVG's animation elements, the scripts modify the base value for the
animation. If a base value is modified while an animation element is animating
the corresponding attribute or property, the animations are required to adjust
dynamically to the new base value.
