/**
* 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.
