Consider using upgraded OpenGL bindings from OpenTK

[andykorth]

It looks like the OpenGL bindings in OpenTK were upgraded a fair bit in September 2014. It includes support for OpenGL 4.5 spec, ES 3.1, and a bunch of fixes. It probably warrants some examination.

Specifically, there were changes both in 1.1 (February) http://www.opentk.com/news/opentk-1.1-stable-released

And additional changes since then, especially in September.

Upgrading some of the math libraries might be nice too.
