  13. I'd like to synchronize the screen refresh with external equipment for
  14. a psychophysical experiment...  I only want a signal coincident with
  15. the FIRST vertical SYNC of the monitor AFTER I call swapbuffers() (i.e.
  16. exactly when the buffers are swapped).  Is there a way to do this?
  17. Thank you!
