[Chimera-users] movie command with headless Chimera

[Tom Goddard]

  Hi Masako,

   Good news.  I fixed the movie command and now it saves movies in 
headless Linux Chimera.  Tonight's daily builds will have the fix.

   One glitch is that movie saving appears to ignore the window size set 
with the windowsize command unless you write out an image with the 
"copy" command before recording the movie.  I've attached the test 
script I used that worked.  I'll file a bug report for that.

     Tom
