You cannot assume from the similar names that the functions are identical. You
need to read the OpenGL ES extension specifications and compare with the OpenGL
specification.
The correct way to fix this is for Emscripten’s OpenGL ES emulation to expose
these functions as the extensions they are. The implementations of those
extensions can share code with the implementations of the similar functions in
the OpenGL emulation.
