[GRASS5] nviz and concave polygons

[Jachym Cepicky]

Hallo,

when I import/create concave polygon, e.g.

    +------------------+
    |                  |
    |                  |
    |     +------+     |
    |     |      |     |
    |     |      |     |
    |     |      |     |
    +-----+      +-----+

echo "F 9 
0 0 5
2 0 5
2 8 5 
8 8 5 
8 0 5
10 0 5
10 10 5
0 10 5
0 0 5"|v.in.ascii -zn out=exmpl format=standard

and when I try to display it with nviz, the polygon is not drawn
correctly, see http://les-ejk.cz/tmp/concave.png

could this be bug in nviz?
