[GRASS-dev] NVIZ now broken?

[Bob Covill]

Hello,

I have been looking into why nviz fails when loading a volume from the
command line (i.e. nviz vol=precip3d.500z50). This is the bug reported
in 
http://intevation.de/rt/webrt?serial_num=4725

It appears that the volume drawmode is not initialized which causes the
GUI to hang when loading the volume panel. The attached patch for
map_obj.c in nviz/src should fix this.
