@chiply @rougier @oantolin This is also why @divyaranjan initially went with SVGs for emacs-reader. See this SVG game from many years ago: https://elpa.gnu.org/packages/slime-volleyball.html.

But soon we realized that SVGs are not good for PDFs because they can contain images which get embedded into the SVG as PNG data, so it much slower anyway. We then switched to directly doing PNG (eventually PPM because we didn't want compression).

Of course, eventually, we realized we need the canvas patch (because we couldn't change the image fast enough).
