[GRASS-dev] North Arrow updates

[Bob Covill]

Hamish & Michael,

I have just applied a couple of changes to NVIZ to pick up some problems
I was having with the new North Arrow args. I have added the updated
arrow routine to togl_flythrough.c (it won't build without it) and I
fixed the number of allowable argc in Ndraw_Narrow_cmd (draw.c).

I have also removed a duplicate place_narrow procedure from
panel_fringe.tcl which was calling Ndraw_Narrow with the old number of
args. I also set the default arrow and text colors in panel_main.tcl to
black (you might want to change these). 

Hopefully this has not broken anything you were trying to do.
