We should allow a configuration file to set up the initial state of the global state, which also implies being able to set the backend. If the allowed backends have already been set programmatically via the clutter_set_windowing_backend(), though, then the application code takes precedence, as we assume that the application author knows better than us what their code supports or requires.
