Gesture Anywhere [1/2]

Add gesture anywhere feature into the ChaOS Lab

When enabled a user can activate the gesture anywhere view by touching
the designated trigger area.  If a gesture is recognized as one the user
has created and assigned to an action, that action will be performed.
Since this is part of the system UI and implemented as an overlay, it
will be available and usable system wide, with the exception of the
keyguard for obvious reasons.
