Hi,
  I would add that if the reason for running the external Tachyon was
to be able to set the resolution, you can normally do that in VMD with the
"display resize" command. That being said, I've started seeing that some
window managers are beginning to disallow window sizes from being larger
than the display, and to address this I'm probably going to have to add new
render command options that allow this to be overridden more universally
so that windowing systems and their window managers don't interfere with
script-based renderings like these.

Cheers,
  John Stone
