All tx/ty (parentX/parentY) usage should be removed from SVG renders

tx/ty are insufficient for passing adequate transform information up the render tree when doing hit-testing or painting.  These are fine for HTML but SVG has more complicated transforms, and thus needs to use things like absoluteTransform() etc, or at least pass a transform object instead.

SVGRenderRoot should be the *ONLY* SVG render class which deals with tx/ty, all others should ignore it. (except maybe the text stuff).

This bug represents removing all usage of tx/ty outside of SVGRenderRoot to finally end all the stupid hit-testing and painting confusion resulting from applying tx/ty too many or not enough times when painting hit/testing SVG renderers.
