Remove unused parameters from setState

[Lukenickerson]

As far as I can tell, the setState function (https://github.com/xem/W/blob/gh-pages/w.js#L131) only uses the state, type, and texture parameters, and does not use i, normal = [], A, B, C, Ai, Bi, Ci, AB, BC.

@xem -- Can these be safely removed?

Oh, nice catch! It seems so.

Hi Luke, I saw your video and it's amazing. Let me know if you want to be an official contributor of this repo (with write access), or chat with me on telegram, whatsapp? I'd be happy to help you and improve W at the same time.

Glad you like the video. Sure, I'd love to be a contributor! I'm also on Discord and WhatsApp.

I added you :)
I've not coded a lot the past year, but slowly getting back to it.
There are features I'd like to add in W, like shadow casting, bump mapping, skybox, ...
I may start prototyping things like this in the future. In the meantime, I'm here if you have questions or critics, and I can't wait for the video #2 !
