What are the extensions to IDirectFBGL2? I guess some config stuff like

The current interface for Qt5 can be seen here[1]. What I am not sure with
DirectFB is if one should use IDirectFBGL and IDirectFBGL2 at the same time
or not. What I think is missing from IDirectFBGL2 is a GetAttribute call to
GetAttributes() returned data from configs that were chosen implicitly so far.
Now, you can specify depth bits etc in DFBGL2ContextDescription before creating
the context, similar to choosing an EGL configuration :)
implement format() and a SwapBuffers().
That's a difficult topic. So far we do
gl->Unlock();
surface->Flip();
gl->Lock();
But that requires all rendering to be flushed for the Flip,
but we're working on a real solution that will prevent all
parallelism across all pipeline stages from vertex buffers
down to the rendered pixels :-D
