Subject: r.composite uses 32767 as NULL value

Platform: Linux/Intel
grass downloaded at: CVS Server, Germany
grass binary for platform: I compiled the sources myself
grass sources source: yes, I am using the latest GRASS from CVS

Hi,

a bug report... When using r.composite on an image, which is smaller than
the current region, the resulting file contains the value 32767 instead of
NULL.

Because of that d.rast -o overlay's won't work.

I've updated G_get_raster_row_colors() to indicate null values, and
fixed r.composite and r.his to propagate null values into the output.
