Add OpenGL 4.4

Please add OpenGL 4.4 spec as this has now been released:

I'll add it soon. Hopefully, before the end of this week.

Ok, it seems that Khronos is finally moving away from the old *.spec file format. That means no OpenGL 4.4 packages at the moment. But I plan to write a parser for the new XML format: https://cvs.khronos.org/svn/repos/ogl/trunk/doc/registry/public/api.

I'm even thinking about a new GoGL 2.0 because of the changes in the latest GL specification documents: e.g. type size guarantees. This will make a lot of things much easier and simpler.

If you don't want to write one from scratch you can contribute to mine.
https://github.com/bryanturley/glgen2 eats the xml spits out

Still a work in progress but give me a week or so.

Hi bryanturley,
that's funny ^^, because Gogl2 is currently under development and my xml parser is more or less done. I plan to create a new repository within the next week or so.

I recommend using xml.Unmarshal to read the xml, it actually works quite well.
