Since this is also in grass 6.x, I worry a little that d.out.* is
too closely tied to the display monitor usage of the other d.*
modules and especially confusion with what d.out.file and
d.out.png do. i.e. nviz_cmd is more a generator than an exporter,
closer in a way to the old p.* paint commands.

also while we are here we should consider the future of d.nviz,
as it is a rather generic name once other options exist too.
I assume that d.nviz in grass 7 will one day be a front-end to
nviz_cmd, with the end-points, vector track, spline fitting, and
time step magic for individual frames performed in d.nviz, and
the actual rendering of each frame done by nviz_cmd in a series
of individual system calls (which could be done in parallel).

maybe d.nviz could call the encoder too? or maybe it would be
cleaner to have a d.3d.movie script around d.nviz and nviz_cmd
for that.


are thoughts about keyframe animation support for wxNVIZ?


perhaps 

d.nviz -> d.nviz.script
nviz_cmd -> d.nviz.image
