Title:
  Unity: should have a setting to disable 3- and 4-finger tap gestures
  (touchscreen)

Status in Unity:
  Triaged
Status in unity package in Ubuntu:
  Confirmed

Bug description:
  Currently, Unity "hijacks" the 3-finger and 4-finger tap gestures
  (3-finger enables multitouch grab handles; 4-finger shows the dash).
  So any applications that want to act on those gestures don't even
  receive them.

  Discussing this with the Unity team, they said it would be feasible to
  add a user-accessible toggle to disable Unity's handling of these
  gestures so they are "passed on" to applications. They asked me to
  file a bug requesting this feature, so here it is.

  My use case is a Qt/QML application that should react to 3- and
  4-finger taps but currently doesn't get the events due to Unity's
  handling of them. The way I get this to work currently is by disabling
  Unity altogether (using compizconfig to disable the unityshell
  plugin), which is a horrendous hack.

  I did find a few bugs that might be related, or be the same feature
  expressed differently, here they are in case triagers decide to mark
  some as duplicates.
