Added vertex array gen/binding and glPolygonMode

Are either of these OpenGL ES 2 calls? I don't see glBindVertexArray or glGenVertexArrays in the spec: http://www.khronos.org/opengles/sdk/docs/man/

Do we want to add gl3.rs? @pcwalton thoguhts?

[jeaye]

Hmm, yeah. That's up to you guys; I've just been adding what I need when I find something that's not there. If necessary, I just won't submit any more pull requests without first checking that it's in OpenGL ES 2.

[pcwalton]

Yeah, how about starting a gl3?

[metajack]

What was the original intent with this library. Now that I'm thinking about it, GL_BGRA and GL_UNSIGNED_INT_8_8_8_8_REV aren't in opengles 2 either (haven't checked 3). Perhaps it should be renamed rust-opengl and restructured to gl.rs (all functions), gles2 (export only stuff in gl.rs that is in ES 2.0), gles3.rs, etc. Then people could just use gl = opengl::gles2;

[metajack]

There's some precendent for this type of structure with core's posix stuff.

[pcwalton]

Yes, I think that would be a better method of organization. Honestly, the library was pretty hacked together—it could use a refactoring.

[metajack]

I'll merge this for now until we do the refactoring.
