Subject:    [PATCH] Don't report old relative values in getValuatorEvents
From:       Chase Douglas <chase.douglas () canonical ! com>

Relative valuator values should not be reported in any future events. If
a relative valuator value is not set in an internal event, set the value
to 0 for XI 1.x valuator events sent over the wire.
