The main feature is <svg> viewBox and proper viewport support, but the CL touches a few other things: * refactor SkSVGRenderContext to auto-restore canvas state, and split the presentation bits into a separate CoW SkSVGPresentationContext * introduce SkSVGNode::onPrepareToRender(), as a way for nodes to push their custom state before the actual onRender() call (instead of relying on non-virtual SkSVGNode to know about all possible state bits) * add a "Type" suffix to SVG types, to disambiguate (e.g. SkSVGRectType vs. SkSVGRect) R=robertphillips@google.com,stephana@google.com GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2222793002 Review-Url: https://codereview.chromium.org/2222793002
