Fail with a message if OpenGL context can't be found

It would be desirable if the Shotcut.app is not failing silently, but offering an error message when there is no OpenGL context to be found. See https://github.com/mltframework/shotcut/issues/427 for related bug.

I agree that without an error we have no clue of what just happened. I guess that the whole interface requires OpenGL, though, meaning that no window was opened. But with python it should be easy enough to get a simple popup to appear.

Actually, there is a thing on startup to try to check for adequate OpenGL and give a warning, but it does not appear to be foolproof for whatever reason:
