There is also this patch

https://codereview.qt-project.org/#change,30554

which looks to add classes that wrap every OpenGL version (not OpenGL ES 3 
yet) and every OpenGL extension. The earlier versions of the patch show 
examples of the classes. The most recent patchsets just include the code 
generator.  Still needs a little more work on integrating it into Qt though.
