> Also, thank you for liaising with the OpenSWR team  in order to check if they support or plan supporting OSMESA.

Frank, I am told that OpenSWR on Github should work with OSMesa. I
haven't tried it out myself, will give it a go once I get the a few
other  issues ironed out. Just wanted to let you know if you wanted to
give it another go.
