Comment:

 It turns out that 2nd order transformation need MORE than 6 points, not 6
 points or more--at least in g.transform. There needs to be a change to the
 help file  about this (for g.transform if different from i.rectify, or for
 i.rectify if in both). I've changed the information in the interactive
 georectify modules for TclTk and wxPython. I'm closing this because it is
 not really a bug (or at least I don't think so), but some misinformation
 in the docs.
