Fix repetitions & by animation support for SVGAnimateTransformElement https://bugs.webkit.org/show_bug.cgi?id=85051 Reviewed by Antti Koivisto. Source/WebCore: Repetitions are currently handled by adjusting percentage (percentage += repeatCount). This doesn't work for <animateTransform> as each repetition has to be post-multiplied to the animated transform list. Fix that. By-animations are equal to values="0;by" animations in SMIL. '0' is the neutral element of addition, which is the _zero_ matrix, not the identity matrix for SVGTransform. Add a new construction mode to SVGTransform to be able to construct zero transforms.
