+ * The event is injected into the event processing, not the EQ. Thus,

+ * original set of classes. Otherwise, the master remains on the XTEST
+ * classes and drops events that don't fit into the XTEST layout (e.g.
+ * events with more than 2 valuators).
+ *
+ * FIXME: EQ injection in the processing stage is not designed for, so this
+ * is a rather awkward hack. The event list returned by GetPointerEvents()
+ * and friends is always prefixed with a DCE if the last _posted_ device was
+ * different. For normal events, this sequence then resets the master during
+ * the processing stage. Since we inject the PointerKey events in the
+ * processing stage though, we need to manually reset to restore the
+ * previous order, because the events already in the EQ must be sent for the
+ * right device.
+ * So we post-fix the event list we get from GPE with a DCE back to the
+ * previous slave device.
