Summary: The mouse polling is also used to detect mouse button press/release events. This is used e.g. by the MouseClickEffect. The XInput2 filter only selected for Raw Motion events which means mouse button events are missed in case it's not combined with a motion. This change makes the input filter also select for raw button press and release events. To support this the X11EventFilter needed to be adjusted to support multiple generic event types to filter for.
