Currently working on getting Emscripten latest working as requirement for PirateJam is webgl submission https://itch.io/jam/pirate

I've been working on a GLFW binding as well rather than HTML5 context binding that is currently being used in ofxEmscriptenWindow.

With GLFW we get ability for multi window system i.e. many canvas
