[GRASSLIST:5914] nviz bug

[Paolo Cavallini]

Hi all.

While revising old bugs, I tried NVIZ, and I found a few problems:
1. dumping at max resolution does not work if I resize NVIZ monitor; it 
produces a number of files:

-rw-r--r--   1 paolo paolo  3133457 2005-02-26 11:05 provamax2_1_1.ppm
-rw-r--r--   1 paolo paolo  3133457 2005-02-26 11:05 provamax2_1_2.ppm
-rw-r--r--   1 paolo paolo       14 2005-02-26 11:05 provamax2_1_3.ppm
-rw-r--r--   1 paolo paolo  3130385 2005-02-26 11:05 provamax2_2_1.ppm
-rw-r--r--   1 paolo paolo  3130385 2005-02-26 11:05 provamax2_2_2.ppm
-rw-r--r--   1 paolo paolo       14 2005-02-26 11:05 provamax2_2_3.ppm
-rw-r--r--   1 paolo paolo       15 2005-02-26 11:05 provamax2_3_1.ppm
-rw-r--r--   1 paolo paolo       15 2005-02-26 11:05 provamax2_3_2.ppm
-rw-r--r--   1 paolo paolo       12 2005-02-26 11:05 provamax2_3_3.ppm
-rw-r--r--   1 paolo paolo        0 2005-02-26 11:05 provamax2.ppm
-rw-r--r--   1 paolo paolo        0 2005-02-26 11:05 provamax2tmp1.ppm
-rw-r--r--   1 paolo paolo        0 2005-02-26 11:05 provamax2tmp2.ppm
-rw-r--r--   1 paolo paolo        0 2005-02-26 11:05 provamax2tmp3.ppm

Of these, the largest are cuts from the whole image.

This is the error output:

I also get an error window:
invalid command name ".dialog0.pw.f1.frame.win.text"

If it's a resize problem only, it should be easy to fix it by making the 
monitor of fixed size.

2. if I switch to another window when dumping, the dump reflects the new 
window instead of the NVIZ monitor. This should be made clear to the user 
"Don't move" message).

3. dumping to IRIS RGB crashes X badly (BTW, is this an useful command? Could 
be safely removed?).

4. when clicking on "nviz" (bottom of "d.nviz" help page) I get an error (does 
not find file:/usr/lib/grass/docs/html/nviz.html).

Grass6.0beta2 from debian testing.

All the best.
