[GRASS5] NVIZ TIFF output (rotated 180 degree)

[Bob Covill]

Markus,

I had noticed that in the past. The place to look for this problem is in 
the ogsf library, in gsd_img_tif.c. This file contains the TIFF header 
info. Probably something in the header is wrong or the actaul image is 
being written wrong (rows / columns).

Hopefully it is something simple.
