1410 | * The event is injected into the event processing, not the EQ. Thus, | |
1411 | * ensure that we restore the master after the event sequence to the | |
1412 | * original set of classes. Otherwise, the master remains on the XTEST | |
1413 | * classes and drops events that don't fit into the XTEST layout (e.g. | |
1414 | * events with more than 2 valuators). | |
1415 | * | |
1416 | * FIXME: EQ injection in the processing stage is not designed for, so this | |
1417 | * is a rather awkward hack. The event list returned by GetPointerEvents() | |
1418 | * and friends is always prefixed with a DCE if the last _posted_ device was | |
1419 | * different. For normal events, this sequence then resets the master during | |
1420 | * the processing stage. Since we inject the PointerKey events in the | |
1421 | * processing stage though, we need to manually reset to restore the | |
1422 | * previous order, because the events already in the EQ must be sent for the | |
1423 | * right device. | |
1424 | * So we post-fix the event list we get from GPE with a DCE back to the | |
1425 | * previous slave device. | |
