The NVIZ image dump for a max resolution PPM creates the file by doing
it one section at a time. After rendering all of the panels it then
stiches them togther. Well when I try this on a Mac with Lorenzo's 5.7
binaries, it broke before it finished and all the panels were dumped
onto the desktop individually. (and the temporarily saved state is
restored)  I don't have the error or computer in front of me to give an
exact error. Hoping someone else could get it. Random guess was that the
OSX version was missing the stitching fn.


Just trying this on Linux (debian/tcl8.3), it works, but the results are
*much* darker than what was on screen. (Happens in 5.3 and 5.7)


These spit out while it is generating:

Creating PBuffer Using GLX 1.3
Create PixMap Using GLX 1.1
Final Assembled Image will be 2048 x 1770
Writing Tile 1 of 4
Writing Tile 2 of 4
Writing Tile 3 of 4
Writing Tile 4 of 4
Assembling Tiles
Destroy Pixmap and GLXPixmap

[file is written ok, the elevation is very dark.. (beyond fixing in GIMP)]


Then, next time I change a knob and redraw the NVIZ display, it breaks:

  Major opcode of failed request:  144 (GLX)
  Minor opcode of failed request:  1 (X_GLXRender)

also saw these when loading/saving state:
