As part of this move properties/methods to the correct subclass
(position related properties go under SVGTextPositioningElement).
SVG text element hierarchy:
SVGTextContentElement
^- SVGTextPositioningElement
^- SVGTextElement
^- SVGTSpanElement
^- SVGTextPathElement (TODO)
^- SVGTRefElement (TODO)
