Well yeah, but I really don´t like linking the OpenGL plugin to hardware 
acceleration libraries.

And while this patch series is untestable, I strongly suspect that it breaks 
VA-DRM support, especially the headless use cases.

I think GLX support is totally useless. GLX is a legacy functional subset of 
EGL. And EGL is supported by those graphics chips that use VA natively.
