Created attachment 464303 [details] Animated example: text scales in steps on WebKit SVG (and HTML) font sizes in WebKit are rounded (wrongfully) creating imprecise layout or making measuring text difficult/impossible. In the attached test case and animated inline SVG with the text not scaling smoothly. Could be related to 149211, 225695 and 240213.
