WebGL2 in std

[scarletjohansson]

I wasn't able to find any discussion about WebGL2 in Haxe. I believe the spec is pretty much at final draft, browser have had implementations for a year (behind a flag), and it makes sense to be able to developed for WebGL2 in anticipation for its likely shipping soon.

What's the process for generating a new set of bindings from the IDLs? I wasn't able to find the generator code in the haxe repro. The WebGL2 IDL is here:

There's a separate "generator" repo, but I can never remember how to use it. I'll look at this next week, but maybe @aduros suddenly shows up and does something about it :)

Chrome and firefox aim to ship webgl2 in january as stated here: https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/VAEv-MUFGC8

Hey @nadako, I've created a PR (HaxeFoundation/html-externs#8) to get the generator repo up and running with the latest WebIDLs. Here's the generated WebGL2 context extern WebGL2RenderingContext.hx

Here's a complete delta for new js.html externs generated from the latest WebIDLs (and then passed through @markknol's html-extern-api-docs to add comments): development...haxiomic:development

Great, I would say, do a pull request 👍

(BTW, I do remember we manually fixed some stupid stuff in these definitions, but can't remember what exactly so we might have to look those up.)

Hey @markknol, I've been reviewing the diff and I unfortunately can see quite a lot of manual changes – I bet we can automate them but since that will take a while, for the time being I'll just PR for the higher priority extern changes like adding WebGL2, updating MediaElement and InputElement

Question for @Simn: do changes to the html externs have to be backward compatible for the 4.0 release? For example, the latest WebIDLs have renamed a few things: VertexArrayObjectOES is now VertexArrayObject and some extensions need to be renamed to avoid conflicts with new WebGL2 versions of the extensions.

WebGL2 externs are now available at js.html.webgl.WebGL2RenderingContext #7354
