Adding/removing SVGPathSeg* items to a SVGPathElement (through SVGPathSegList interface) has live updates problems, as the notifyAttributeChange() function isn't called anywhere. The context param is currently stored per SVGPathSeg, which is not needed - as it can be done using SVGPathSegList completely. It wastes memory, that is fixed. In order to get rid of the context param in SVGPathSeg, we need a way to map SVGPathSeg* objects to SVGStyledElement* objects ("context element"). That is done using a new HashMap in the SVGDocumentExtensions class.
Attaching patch soon.
