godot/platform/javascript/audio_driver_javascript.h
Fabio Alessandrelli e2083871eb [HTML5] Port JavaScript inline code to libraries.
The API is implemented in javascript, and generates C functions that can
be called from godot.
This allows much cleaner code replacing all `EM_ASM` calls in our C++
code with plain C function calls.
This also gets rid of few hacks and comes with few optimizations (e.g.
custom cursor shapes should be much faster now).
