[GRASS5] Referencing jpeg images without display

[Michael Barton]

David,

I.rectify rectifies images without a graphic interface. It just needs a
points file with GCP's in it. I.points uses a graphic interface to generate
the points file of GCP's from an already rectified map. However, if you
generate them in another way, it is not necessary.

Also, the GDAL utility gdalwarp can rectify and georeference an image. It
can use GCP's embedded in the image file (e.g. Terra ASTER HDF files) or an
external GCP file.
