[chimera-dev] accelerators and stereo

[Thomas Goddard]

Hi Matthew,

  Ok I think I have it right now.  The code below where I've added
a second argument to the c.setMode() call now makes the F1 function
key toggle between stereo and mono.

  Sorry the previous code did not work.  I tested it with "cross-eye
stereo" because my machine did not have hardware stereo and that
worked with the previous code.  But when I tested with hardware stereo
I found that it needed the second argument to the setMode() function.

     Tom
