Hi Sergey,

as requested I have submitted my branch for review and further discussion

https://developer.blender.org/D583


Open issues

- - display and final result in Compositor not 100% correct
  Not sure if the automation isn't working, or if the wiring of the nodes
  and thus the sequence of transformation operations is not correct.

- - initialisation and calculation of auto-scale iterates over all frames,
  but doesn't use the automated values at those frames.
  Still need to find out how this can be done.

Sorry, not yet.
But there is a demo blend file in my git repo.

How to use this demo
~~~~~~~~~~~~~~~~~~~~

  1) open the "Default" view (3D View). This simple animated scene will be
     our test footage. Render the 300 animation frames to the preconfigured
     path (//stab/testfame-####.png)

  2) swtch to the "Motion Tracking" screen. Be sure not to erase the tracking
     data that is already there. Just load the rendered test frame.

  3) play with the settings in the "Stabilize 2D" pane....

NOTE: Auto-scale looks as if it is broken. It is not -- just the movement
of this demo clip is so extreme as to render autoscale useless
