* 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.
