Repaint SVG subtree on viewport changes (resize)
When the (outermost) <svg> is sized using percentages, and an ancestor
changes size, the LayoutSVGRoot will be marked for layout (even though
the dimension/initial viewport changes.)
Since changed dimensions can imply a new scale factor (for instance from
interactions with a viewBox) or previously clipped content being
exposed, we need to issue paint invalidations for the entire SVG.
