WebGL Code cleanup? about herebedragons

[kosua20]

First of all, thanks a lot for all this feedback!
I must apologize as I've realized that the WebGL version was in a worst state than I remembered...

As a learning experience I've tried to correct some of the aberrations that were present in my version (your remarks and your website were extremely useful, thank you again!). I've committed these changes, but I must admit that I have almost no experience with Javascript so some more general JS anti-patterns might remain in my code.
I have also removed the fixed resolution and the failed/unneeded attempt at handling HiDPI screens (in the C++ version I am using a fixed vertical rendering resolution), and now rely on CSS only.

Concerning VBO and extensions, my initial goal was to write a basic WebGL 1 version without any extensions as a kind of lowest common denominator. Maybe a WebGL 2 version with extensions would be different enough to live in its own webgl2 directory?

WebGL2 should probably be in another folder if you want to do that and you won't need extensions for vertex array objects. You can also do uniform buffer objects in WebGL2 but they are a little funky because there is no glMapBuffer in WebGL2.

My point with vertex array objects for WebGL1 is they're available on 99% of machines so for all intents and purposes they aren't are really an extension if that makes any sense. I'm only pointing that out if you wanted to try to keep the code similar since the C++ is using VAOs. Of course you can also leave it as is.

Thanks for the cool example. It's great to see so many versions.
