RenderSVGContainer does not mark itself for repaint after setting viewBox, slice or align
It should invalidate itself when these change.
Rob fixed the viewBox case. Others are trivial to fix, too.

This is fixed nowadays. Changing ie. slice is only possible through JS, either by setting preserveAspectRatio attribute or by using SVG DOM directly, both cases cause a svgAttributeChanged(preserveAspectRatioAttr) call to be fired on the individual SVG*Element classes, causing them to call setNeedsLayout(true) on their renderer. It also works for resources and instances of elements, so it's really fixed today :-) Closing bug.
