+ * Changes the screen reference events are being enqueued from.
+ * Input events are enqueued with a screen reference and dequeued and
+ * processed with a (potentially different) screen reference.
+ * This function is called whenever a new event has changed screen but is
+ * still logically on the previous screen as seen by the client.
+ * This usually happens whenever the visible cursor moves across screen
+ * boundaries during event generation, before the same event is processed
+ * and sent down the wire.
+ *
+ * @param pDev The device that triggered a screen change.
+ * @param pScreen The new screen events are being enqueued for.
+ * @param set_dequeue_screen If TRUE, pScreen is set as both enqueue screen
+ * and dequeue screen.
