Nikolas Zimmermann
The anonymous RenderSVGViewportContainer, enclosing all descendants of the outermost <svg> element, is usually created when the first child is supposed to be added to the <svg> element. This logic fails, if there is no descendant. This creates problems when one wants to compute getCTM() / getScreenCTM() matrices for such a <svg> element -- the viewBox transformation would be ignored, since it is supposed to be handled via the RenderSVGViewportContainer, which is not there -> fix that.
