// SVGImage does not use Skia to draw images (as BitmapImage does) but instead
// handles drawing itself. Internally, SVGImage creates a
// IsolatedSVGDocumentHost and reuses the existing paint code in Blink to draw
// the image. Because a single SVGImage can be referenced by multiple
// containers (see: SVGImageForContainer.h), each call to SVGImage::draw() may
// require (re-)laying out the inner SVGDocument.
//
// Using Page was an architectural hack and has surprising side-effects. Ideally
// SVGImage would use a lighter container around an SVGDocument that does not
// have the full Page machinery but still has the sandboxing security guarantees
// needed by SVGImage.
