+// 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.
+
+
+/* Example Usage:
+	// Load SVG
+	NSVGimage* image;
+	image = nsvgParseFromFile("test.svg", "px", 96);
+	printf("size: %f x %f\n", image->width, image->height);
+	// Use...
+	for (NSVGshape *shape = image->shapes; shape != NULL; shape = shape->next) {
+		for (NSVGpath *path = shape->paths; path != NULL; path = path->next) {
+			for (int i = 0; i < path->npts-1; i += 3) {
+				float* p = &path->pts[i*2];
+				drawCubicBez(p[0],p[1], p[2],p[3], p[4],p[5], p[6],p[7]);
+			}
+		}
+	}
+	// Delete
+	nsvgDelete(image);
