Subject: r.in.gdal: UInt16 colr map goes to full 65535

I just r.out.gdal'd a DEM as UInt16 which copies out the color table.

Then as a check I reimported it with r.in.gdal.

The "COPYING COLOR TABLE" took a while.

d.rast took a long while too. (killed it)


Turns out that while my file had values ~ 0-1000, the colr/ file had entries
of "0" for each int up to 65535  (as does the GeoTIFF as shown by gdalinfo*).
vi took care of that. :)

[*]  Color Table (RGB with 65536 entries)


Two things would be nice:

a) r.out.gdal shouldn't export 64k color tags, only up to max
b) r.in.gdal is smart enough to add as the last colr rule max:0 65535:0  ?



thanks,
Hamish
