0001-remove-NX_NUMPROCS-case.patch

Subject: [PATCH 1/3] remove NX_NUMPROCS case

1) NX_NUMPROCS isn't supposed to be an event number, but just the number of
   events from NX_FIRSTEVENT to NX_LASTEVENT
2) NX_NUMPROCS is > NX_LASTEVENT, so the "default:" branch already
   handles it (and shows a warning)

0002-don-t-ignore-unknown-events.patch

Subject: [PATCH 2/3] don't ignore unknown events

Ignoring and filtering unknown events may have unknown consequences.
e.g.:
http://synergy-foss.org/spit/issues/details/3195/

By removing the hack, the behavior will be:

- the "default:" branch will be run, showing a warning with event ID
- the event will be filtered out if focus is on a different screen,
  and will be not filtered if the server is the current screen

Subject: [PATCH 3/3] don't generate warnings for known trackpad-specific
 events

The current behavior will be kept: events will be filtered out if the
screen doesn't have focus, and forwarded unchanged if it has focus.
