https://www.w3.org/TR/SVG11/struct.html#ImageElement https://www.w3.org/TR/SVG11/coords.html#PreserveAspectRatioAttribute We already had a function to compute the appropriate matrix, and since we can share the functionality with other elements that establish a new viewport (including svg, symbol, and a few others), this CL moves the function to the SVG node base class. Relevant test for images is struct-image-06.
