 I'm happy to announce, that we modified Georeferencer
  extension and want other developers to try it out sometime (I know
  we're in freeze, but we needed this functionality). We did some testing
 on Preview2 and everything works really well (except annoying potentiall
  GDAL bug with 6 points in 2nd order polynomial, which is being discussed
 in its
  trac right now).

  What we did: we've added the ability to use 1-2-3rd order polynomials
  via GDAL functions to transform rasters.
  Why: Helmert transform performance implemented before was
  sub-suboptimal
  How: Built ontop of existing Georeferencer extension (basically added
  three new transforms to the list)
  Next: We're doing some more modifications of Georeferener, but they're
  minor.
