[GRASS5] g3d success

[John Harrop]

I've modified the loops in s.vol.idw and r3.out.v5d to follow the same 
pattern:

all loop counters increment.

easting starts in the west and increments.
northing starts in the north and decrements.
level starts at the top and decrements.

When I regrid a 3d site file, and then export it to v5d format, the data 
loads into vis5d with all the axes orientationed correctly!  I guess 
that shouldn't be too suprising ;-)  I'm getting on to the other modules 
as time permits.

Does someone want me send you files, or is that so trivial you can just 
make the change?

Cheers,

John Harrop
