To support toolkits targeting wayland and using Cogl we allow toolkits to be responsible for connecting to a wayland display and asking Cogl to use the toolkit owned display and compositor object. Note: eventually the plan is that wayland will allow retrospective querying of objects so we won't need the foreign compositor API when Cogl can simply query it from the foreign display.
