I tried it and here are the results in comparison:
  capture: 
http://www.fli-leibniz.de/~rhuehne/jmol/bupropion-capture-antialias_off.gif

  PNGT->Gimp: 
http://www.fli-leibniz.de/~rhuehne/jmol/bupropion-movie-antialias_off.gif

The Gimp movie still looks considerably better (smoother, less dotted) 
than the improved Jmol movie.

For 'capture' I used the following commands after setting the window 
size to get the image resolution of 1362x617 pixel:
---------------------
background yellow;
set antialiasImages off;
animation mode loop
animation fps 7
ndegrees = 2
nFrames  = 180
capture "bupropion-capture-antialias_off.gif" 1000 transparent;
for (var i  = 1; i<= nFrames; i++) {
    rotate x @ndegrees;
    refresh;
}
capture;
--------------------

For PNGT export I used the following commands:
---------------------
set antialiasImages off;
exportAnimation("bupropion-movie","1362", "617", "180", "rotate 
axisangle {1 0 0} 2", "yellow")
---------------------
And in Gimp I manually applied indexing to 255 colors using the 
Floyd-Steinberg dithering option with reduced color bleeding.
During export as GIF I set the delay to 140ms and the disposal method to 
'one frame per layer (replace)'.

Regards,
Rolf
