Re: NeXT geomview problem(s)

This is most likely a driver bug. I'll look into it.

Subject: NeXT geomview problem(s)

My main problem is illustrated  in this geom--a single two-segment  
path:

 (new-geometry TopD {VECT

# This file created by method - outputGeomview of ObjectGrid.
# We have 1 polylines, 3 verticies and 0 colors.
1   3   0
# Next, the number of verticies in each polyline:
3 

# Next, the number of colors in each polyline, zero in this case:
0 

# And now the list of verticies--plain vanilla, nothing added
136.000000 634.000000 0.000000
430.000000 397.000000 0.000000
208.000000 236.000000 0.000000
# that's all she wrote, folks
})


On SGI it displays correctly, but on a NeXT it appears as a closed  
path (triangle).

For other files, similar behavior--two non-closed paths turn into two  
closed paths etc.

My guess is that the NeXT version is (somehow) tripping up on the  
rule (from the oogl man pages)

Next come <NLines> integers
	   Nv[0] Nv[1] Nv[2] ... Nv[<NLines-1>]
	giving the number of vertices in each polyline.  A negative  
number
	indicates a closed polyline;...............

A second problem is/seems less serious.  If a module is started in  
geomview and we quit geomview, the module is not terminated.
