Haxe

that takes care of the sizing - sorry misunderstood your question about

`                var gl = context.webgl2;
`

for peote-view i do check before whats possible by this: <https://github.com/maitag/peote-view/blob/master/src/peote/view/PeoteGL.hx#L104>

(you also have the gl-extensions to do more if you _enable_ it)

my guess is that there is no render context yet assigned - you either need to check and do nothing until one is or get it from another cbk. The lime examples show how to boot the app so you get a GL context.

it worked fine though when I had webgl instead of webgl2

yep, VAO should work only for webgl2 or gles3 (same for UBO and instance-drawing)

ok I used html5 with webgl2, and it launches but no triangle 💀

ah, to use `layout` inside of shader you have to tell what version

put a `#version 300 es` on top of glsl-code
