    The new calibrator uses weston_touch_calibration protocol extension and
    provides the following features:
    
    - chooses the physical touch device to be calibrated by DEVPATH or by
      the output/head name; device enumeration provided
    
    - the compositor ensures the calibrator window is shown in the correct
      position and size
    
    - no matter how wrong the old calibration is, the touch events will
      always arrive in the application
    
    - the calibration is complete, not incremental; the received touch
      events are guaranteed to be unmodified
    
    - computes a libinput style calibration matrix directly, not the
      WL_CALIBRATION format
    
    - supports multiple touch devices: calibrate one device at a time, and
      show user feedback on touching a wrong device instead of recording bad
      data
    
    - uses four touch point samples: three to compute the calibration, and
      one to verify the calibration is roughly correct
    
    - consistent exit codes
    
    - upload the new calibration into the server after suc...
