Automatic update from web-platform-tests [GeometryInterface] add scaleNonUniform method in DOMMatrixReadOnly DOMMatrix should be alias to SVGMatrix. (It was not implement in blink yet) SVGMatrix have scaleNonUniform() function. but DOMMatrix was not. there are some website which is used SVGMatrix.scaleNonUniform(). it would be possible brake some website when DOMMatrix be alias to SVGMatrix. Intent to implement and ship: https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/BJJKDby5p7w Bug: 905921 Change-Id: Ic09b8d6e46d0aa822b766bd6cfbc5ce7c2164849 Reviewed-on: https://chromium-review.googlesource.com/c/1341279 Commit-Queue: Hwanseung Lee <hs1217.lee@samsung.com> Reviewed-by: Philip Jägenstedt <foolip@chromium.org> Reviewed-by: Fernando Serboncini <fserb@chromium.org> Reviewed-by: Jinho Bang <jinho.bang@samsung.com> Cr-Commit-Position: refs/heads/master@{#612473} -- wpt-commits: 3035063af73d90ecedce301411152855cd66e59d wpt-pr: 14281
