If you look at the code more closely you'll see that EGL_CONTEXT_CLIENT_VERSION
is set regardless of the API and presence of KHR_create_context. Both of which
rather important :)
With that said, I'll repeat my request - please flesh out a simple test app
(which does not depend on QT), before we jump on the pointing fingers train :-P
