I have a new problem:
Raylib-d [can see all 6 gamepad 
axes](https://github.com/jwatson-CO-edu/nanoverse/blob/main/d/raylib/04_jsInput/source/app.d#L44).  However, they [all return 0](https://github.com/jwatson-CO-edu/nanoverse/blob/main/d/raylib/04_jsInput/source/app.d#L48) for all stick motion.

Do I need to initialize the gamepad somehow?
