[GRASS-user] Workflow to generate full resolution composite images

note you can use the d.out.file size= option in place of GRASS_WIDTH and GRASS_HEIGHT.

also a georegistered GeoTIFF is available for output, see:
  http://grass.osgeo.org/grass64/manuals/html64_user/d.out.file.html

but generally it is better to export RGB bands as a group to create
a three band GeoTIFF. Pass r.out.gdal an imagery group to do this.
