Cancel touch events when a low-level touch gesture occurs.
When the touch firmware or driver sends a key event that is triggered
by a low-level gesture such as a palm slap. For this to work, the
touch device's .kl file must specify the "GESTURE" flag for each
key that is produced by a gesture.
Note that the "VIRTUAL" flag should also be specified for any such
keys for which we would like to generate haptic feedback.
eg. key 142 SLEEP VIRTUAL GESTURE
