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

+ * ensure that we restore the master after the event sequence to the

+ * 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.

+ *

+ * First one on drinking island wins!
