OpenGL 4.6 support

[kjozic]

When can we expect support for OpenGL 4.6?

It should be straightforward to generate the new bindings. I'll try and make time this week to do it.

When I try to generate the new bindings using glow (glow generate -out=./v4.6-core/gl/ -api=gl -version=4.6 -profile=core -xml=../glow/xml/) following error occurs: 2017/11/05 12:32:03 unable to generate package: &{gl 4.6 core /home/kreso/golang/src/github.com/go-gl/glow/tmpl <nil> <nil> false}

That error happens on this line:

https://github.com/go-gl/glow/blob/75d9c6716e5939e941a3fc5e2d6afaf36f52514d/main.go#L123

If it happens, that means spec.HasPackage(packageSpec) was not true for any of the specs in the XML directory.

It looks like we need to update the contents of the XML directory with the latest XML specifications. The ones currently there now only have 4.5, not 4.6.

@errcw Is it documented anywhere how to update the contents of the XML directory? I can't find it (not in the README of the repo, nor in the README within the xml directory, nor in wiki).

Edit: I found there's a glow download command for it.

I found the files in the following locations: https://raw.githubusercontent.com/KhronosGroup/OpenGL-Registry/master/xml/gl.xml https://raw.githubusercontent.com/KhronosGroup/OpenGL-Registry/master/xml/glx.xml https://raw.githubusercontent.com/KhronosGroup/OpenGL-Registry/master/xml/wgl.xml https://cvs.khronos.org/svn/repos/ogl/trunk/doc/registry/public/api/egl.xml

Glow successfully generates OpenGL 4.6 core and compatibility bindings using these files.

We need to decide to how to proceed in https://github.com/go-gl/glow/issues/90 to make progress on this issue.

[dmitshur]

Now that https://github.com/go-gl/glow/issues/90 is resolved, we can proceed here.

I've created PR #92 that'll resolve this issue (it's an updated version of #90).
