/**
* clutter_input_device_update_from_event:
* @device: a #ClutterInputDevice
* @event: a #ClutterEvent
* @update_stage: whether to update the #ClutterStage of the @device
* using the stage of the event
*
* Forcibly updates the state of the @device using a #ClutterEvent
*
* This function should never be used by applications: it is meant
* for integration with embedding toolkits, like clutter-gtk
*
* Embedding toolkits that disable the event collection inside Clutter
* need to use this function to update the state of input devices depending
* on a #ClutterEvent that they are going to submit to the event handling code
* in Clutter though clutter_do_event(). Since the input devices hold the state
* that is going to be used to fill in fields like the #ClutterButtonEvent
* click count, or to emit synthesized events like %CLUTTER_ENTER and
* %CLUTTER_LEAVE, it is necessary for embedding toolkits to also be
* responsible of updating the input device state.
*
* For instance, this might be the code to translate an embedding toolkit
* native motion notification into a Clutter #ClutterMotionEvent and ask
* Clutter to process it:
*
* |[
* ClutterEvent c_event;
*
* translate_native_event_to_clutter (native_event, &c_event);
*
* clutter_do_event (&c_event);
* ]|
*
* Before letting clutter_do_event() process the event, it is necessary to call
* clutter_input_device_update_from_event():
*
* |[
* ClutterEvent c_event;
* ClutterDeviceManager *manager;
* ClutterInputDevice *device;
*
* translate_native_event_to_clutter (native_event, &c_event);
*
* /* get the device manager */
* manager = clutter_device_manager_get_default ();
*
* /* use the default Core Pointer that Clutter
* * backends register by default
* */
* device = clutter_device_manager_get_core_device (manager, %CLUTTER_POINTER_DEVICE);
*
* /* update the state of the input device */
* clutter_input_device_update_from_event (device, &c_event, FALSE);
*
* clutter_do_event (&c_event);
* ]|
*
* The @update_stage boolean argument should be used when the input device
* enters and leaves a #ClutterStage; it will use the #ClutterStage field
* of the passed @event to update the stage associated to the input device.
*
* Since: 1.2
