REVISION SUMMARY
  This change introduces a damage tracking feature in SurfaceInterface.
  So far the SurfaceInterface only exposes the damage compared to the
  last attached buffer. But this is not always usefull for the user of
  the library. E.g. if:
  
  - server renders
  - client damages buffer and commits
  - client damages buffer and commits
  - server wants render
  
  In this situation the last damage information is not helpful to the
  user of the library. It would need the combined damage information over
  all attached buffers.
  
  The new API combines the damage of the two commits in the example above.
  The user of the library can then call resetTrackedDamage once it
  processed the current damage (e.g. by updating the OpenGL texture).
