stereo format to work.  It's a good thing I tested these on a TV
before submitting them since I did indeed have a bug.  One thing I
did not test was to see how this would work in windowed mode.  Does
the interlaced stereo code have support for 'absolute' positions?
For example a given pixel on the screen is always shown in a given
eye no matter where the graphics context is placed?
