I just posted a message which requires the same answer...

Look at the code in /usr/share/Performer/src/lib/pfutil/xwin.c

Also look at the public domain source code glxinfo.c (try

searching on sourceforge)

You need to find out if you have any stereo visuals, and

then pick a specific visual that gives you stereo and

your best (deepest) depth,red-size,green-size,glue-size

etc. Or... no stereo is available but you still pick

your best of everything else.

These two programs gave me the hints I needed. Also

take a look at wglinfo.c source (found on sgi.com)

to do the same thing on MS-Windows.

Good Luck!
