// 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 NanoVG should be one of: 'px', 'pt', 'pc' 'mm', 'cm', or 'in'.
+// 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
- SNVGImage* image;
- image = nsvgParseFromFile("test.svg", "px", 96);
- printf("size: %f x %f\n", image->width, image->height);
- // Use...

- for (path = shape->paths; path != NULL; path = path->next) {

- 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);
