// NanoSVG is a simple stupid single-header-file SVG parse. The output of the parser is a list of cubic bezier shapes.
//
// The library suits well for anything from rendering scalable icons in your editor application to prototyping a game.
//
// NanoSVG supports a wide range of SVG features, but something may be missing, feel free to create a pull request!
