The input device API is split halfway thorugh the backends in a very weird way. The data structures are private, as they should, but most of the information should be available in the main API since it's generic enough. The device type enumeration, for instance, should be common across every backend; the accessors for device type and id should live in the core API. The internal API should always use ClutterInputDevice and not the private X11 implementation when dealing with public structures like ClutterEvent. By adding accessors for the device type and id, and by moving the device type enumeration into the core API we can cut down the amount of symbols private and/or visible only to the X11 backends; this way when other backends start implementing multi-pointer support we can share the same API across the code.
