Please correct me if I am wrong. It seems to me that OpenGL doesn't support
enumerating the adapters. Yes, OpenGL can get the device UUIDs if the extensions exist.
But it binds to current OpenGL context. Since we don't have a way to correlate DISPLAYs
to adapters, I don't see a way to enumerate adapters via OpenGL.
