GRASS component: raster

Initial Comment:
In spearfish, r.in.gdal the attached lines.tif and run:

$ g.region rast=lines -a
$ r.to.vect input=lines output=lines_vect feature=line

Display the raster and vector and see how vector is off the raster - like in the attached screendump off.png. It *seems* the problem is that the output vector is moved half the cell resolution east (this is visible on both the vertical and horizontal line).
