At this point, I could roll my own system for interaction between the WebAssembly module and the JavaScript WebGL library. That would involve using a function table to call the JavaScript WebGL functions from within C++. Luckily for us, the Emscripten team has done most of this work. They have created a port of a popular 2D C++ graphics library that does this for us. SDL is a 2D graphics Application Programming Interface (API) built on top of OpenGL in most implementations. There is an Emscripten port that is used to help us render our 2D graphics on top of WebGL. If you would like to know what other libraries have been integrated into Emscripten, use the following emcc command:
emcc --show-ports
If you run this command, you will notice that several different SDL libraries are displayed. These include SDL2, SDL2_image, SDL2_gfx, SDL2_ttf, and SDL2_net...
