This enables basic Emscripten support in Cogl via the SDL winsys. Assuming you have setup an emscripten toolchain you can configure Cogl like this: emconfigure ./configure --enable-debug --enable-emscripten Building the examples will build .html files that can be loaded directly by a WebGL enabled browser. Note: at this point the emscripten support has just barely been smoke tested so it's expected that as we continue to build on this we will learn about more things we need to change in Cogl to full support this environment.
