The ::drag-motion signal does not have a ModifierType argument; also,
there's no need to connect to the ::drag-motion signal any more.

* all the necessary logic for dragging actors.
*
* The simplest usage of #ClutterDragAction consists in adding it to
* a #ClutterActor and connecting to the #ClutterDragAction::drag-motion
* signal handler to move the actor; for instance:
* a #ClutterActor and setting it as reactive; for instance, the following
* code:
*
* |[
* ClutterAction *action = clutter_drag_action_new ();
*
* g_signal_connect (action, "drag-motion",
* G_CALLBACK (on_drag_motion),
* NULL);
*
* clutter_actor_add_action (actor, action);
* clutter_actor_add_action (actor, clutter_drag_action_new ());
* clutter_actor_set_reactive (actor, TRUE);
* ]|
*
* Where the on_drag_motion() signal handler calls clutter_actor_move_by()
* using the delta between motion events passed to the handler:
* will automatically result in the actor moving to follow the pointer
* whenever the pointer's button is pressed over the actor and moved
* across the stage.
*
* |[
* static void
* on_drag_motion (ClutterDragAction *action,
* ClutterActor *actor,
* gfloat delta_x,
* gfloat delta_y,
* ClutterModifierType modifiers)
* {
* clutter_actor_move_by (actor, delta_x, delta_y);
* }
* ]|
* The #ClutterDragAction will signal the begin and the end of a dragging
* through the #ClutterDragAction::drag-begin and #ClutterDragAction::drag-end
* signals, respectively. Each pointer motion during a drag will also result
* in the #ClutterDragAction::drag-motion signal to be emitted.
*
* It is also possible to set another #ClutterActor as the dragged actor
* by calling clutter_drag_action_set_drag_handle() from within a handle
