I spent a couple hours to integrate nanovg (https://github.com/memononen/nanovg) into the oryol engine, and it runs pretty well through emscripten (number of GL calls is pretty high):
http://floooh.github.io/oryol/TestNanoVG.html nanovg (almost) didn't require any changes, one fix I did was to remove the fairly excessive calls to glGetError since this killed performance in Chrome, and non-power-of-2 textures didn't render because the GL_TEXTURE_WRAP_S/T modes need to be set to GL_CLAMP_TO_EDGE. Another thing I had to fix in the demo scene was resource loading (fonts and images), nanovg either can load directly from file via fopen/fread/fclose, but also can create from file-data in memory. I used the create-from-memory functions and asynchronous resource loading to create fonts and images deferred, and skipped parts of the demo scene rendering if a required resource isn't available yet. I think a really useful optimization for nanovg would be to try reducing the number of GL calls.
