// 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!
//
// The shapes in the SVG images are transformed by the viewBox and converted to specified units.
// That is, you should get the same looking data as your designed in your favorite app.
//
// NanoSVG can return the paths in few different units. For example if you want to render an image, you may choose
// to get the paths in pixels, or if you are feeding the data into a CNC-cutter, you may want to use millimeters.
//
// The units passed to NanoSVG should be one of: 'px', 'pt', 'pc' 'mm', 'cm', or 'in'.
// DPI (dots-per-inch) controls how the unit conversion is done.
//
// If you don't know or care about the units stuff, "px" and 96 should get you going.
