Which Copyleft Licence is Suitable for an SVG?

The Scalable Vector Graphics (SVG) format is amazing. It allows you to precisely define how an image should look. Written in XML, it uses various mathematical operations to display an image which looks crisp and clear at any size. Here's a trivial example: <svg height="100" viewBox="0 0 100 100" width="100" xmlns="http://www.w3.org/2000/svg"> <circle cx="50" cy="50" fill="#fff" r="100"/> </svg> That code produces this circle: You could print that out with a kilometre radius and it would still be a perfect circle - unlike a traditional raster image which is just a grid of blocky pixels.
