commit eec7f6e24d8f7a36db5529969ca17087edf37b76
Author: Zeno Albisser <zeno@webkit.org>
Date:   Wed Oct 24 16:04:15 2012 +0200

    Add glxContextForContext function to QXcbNativeInterface.
    
    This change enables receiving the native GLXContext object that is used
    by a QOpenGLContext in case of GLX.
    This clearly is non-public api that is only meant to be used as a
    last resort for cases where it is really necessary to get hold of
    a native context object.
