Demo on how to use OpenGL-Psychtoolbox to present stereoscopic stimuli.
DEPRECATED! THIS DEMO ONLY DEMONSTRATES THE LEGACY STEREO SUPPORT!
If you have a recent graphics card, have a look at ImagingStereoDemo.m
instead. It demonstrates a much better, more flexible, robust way of
presenting stereo stimuli with Psychtoolbox.

stereoMode specifies the type of stereo display algorithm to use:
0 == Mono display - No stereo at all.
2 == Top/bottom image stereo with lefteye=top also for use with special
3 == Same, but with lefteye=bottom.
4 == Free fusion (lefteye=left, righteye=right): This - together wit a
screenid of zero - is what you’ll want to use on MS-Windows dual-display
setups for stereo output.
5 == Cross fusion (lefteye=right …)
6-9 == Different modes of anaglyph stereo for color filter glasses:
6 == Red-Green
7 == Green-Red
8 == Red-Blue
9 == Blue-Red
10 == Dual-Window stereo: Open two onscreen windows, first one will
display left-eye view, 2nd one right-eye view. Direct all drawing and
flip commands to the first window, PTB will take care of the rest. This
mode is mostly useful for dual-display stereo on MacOS/X. It only works
on reasonably modern graphics hardware, will abort with an error on
11 == Like mode 1 (frame-sequential) but using Screen’s built-in method,
instead of the native method supported by your graphics card.
