OSX OpenGL capabilites matrix
-------------------------------

The ``GL_ARB`` extension system means that correspondence between an  OpenGL feature and the OS  implmentation
is not cut and dryed.  Hence the matrix:

However:

* For OSX 10.9 (Mavericks, Oct 2013) compatibility only extends up to features from OpenGL 4.1 
* For OSX 10.8.5 () compatibility only extends up to features from OpenGL 3.2
