The Skia team noticed SVG overzealously saves and restores contexts. SVGTextRunRenderingContext has a particularly egregious case where we save/restore on every text run just for stroke thickness: http://trac.webkit.org/browser/trunk/Source/WebCore/rendering/svg/SVGTextRunRenderingContext.cpp?rev=133290#L145 Saves and restores are not free and we can pick up performance by avoiding them.
