[GRASS5] NVIZ: Marooned

[Bob Covill]

Hi Massimo,

I have found a couple of side effects related to the recent updates. 
They are probably related to the message below.

The first (fairly minor) is that height slider is not updated when 
switching back and forth between the "eye" view and "fly" view. This 
should be a fairly straight forward to fix. We probably just need to add 
something in the change_display procedure in panel_main.tcl to update 
the new height.

I have also noted that if in fly-mode the position panel does not pick 
up the correct "real" to-from positions. If you open the "eye" and 
"center" view menus the correct(?) "real" to-from position is set.

Lastly, I created a small fly-through with the "fly" menu (which worked 
really well) and saved it from the keyframe panel. The fly-through 
re-played fine in the current session, but when I re-start NVIZ and load 
the saved animation, the keyframe positions are off.

I suspect that most of these problems are related. I will try and 
investigate a little further.
