[Gvsig_english] recommended raster exchange format

[Benjamin Ducke]

The r.out.gdal module is not very good at guessing the right data type
for your data. You may need to experiment a bit with the "type" option.
If your data is floating point, try

type=Float64

In that case, of course, you will not be able store cell colours
directly in the TIFF file, meaning that you have to re-create
your palette in gvSIG.
