説明
as discussed here, today the only information that emscripten returns about WebGL context creation failures appears in logs, if the GL_DEBUG or ASSERTIONS flags are set during the build process. There's no programatic way of receiving the source of failure in GL.createContext or emscripten_webgl_create_context, which means that these failures can't be handled in real time, and any logs must be extracted from the console - both of which are problematic when shipping code for production.
Something like the proposed emscripten_webgl_create_context_ex should be created, preferably with the ability to extract error information from also from the internal call to GL.createContext.
