 The drawing context is created using platform specific constructor function. If you're using the default OpenGL 2.0 back-end the context is created as follows:
 ```C
-struct NVGcontext* vg = nvgCreateGL2(512, 512);
+struct NVGcontext* vg = nvgCreateGL2(512, 512, NVG_ANTIALIAS);
 ```
 The two values passed to the constructor define the size of the texture atlas used for text rendering, 512x512 is a good starting point. If you're rendering retina sized text or plan to use a lot of different fonts, 1024x1024 is better choice.
