SVGAnimationElement subclasses need to support absolute time calculations Currently SVGAnimationElement subclasses only support relative time calculations. For example most save off an m_lastValue to use when repeating. This is wrong, as an animation may not actually ever complete one repetition before being asked to render a later time, at least once bug 12073 is implemented.
Is this bug still valid? Dirk?
This is fixed since a long while - at least two years, since we switched to the SVGAnimatedTypeAnimators.
