Hi Mike,

Big fan of PyOpenGL! Just wanted to offer this simple patch for the most
recent version of master, which adds a handle for OSMesa's
OSMesaCreateContextAttribs
<https://github.com/anholt/mesa/blob/01e511233b24872b08bff862ff692dfb5b22c1f4/include/GL/osmesa.h#L167>
function.
This function allows for users to create OSMesa contexts with core
profiles, which is hugely useful for supporting offscreen rendering with
modern (>=3.3) shaders.

My only concern is that this function is new in Mesa 11.2, which was
released on April 4, 2016, so this might not work with older Mesa versions.
Not sure if the compilation system will handle this smoothly or not.
Suggestions are welcome, happy to help modify this as needed.

Best,
Matthew Matl
UC Berkeley EECS PhD Candidate
