I'm reviving an old post here.  It seems that we could effectively
query for OpenGL stereo rendering support if the two-stage creation
mechanism was still allowed for wxGLCanvas.  The Create() function for
the wxGLCanvas seems to provide the functionality we need (and also
does the initialization we'd want) and returns a boolean indicating
success.  Just checking the return value would tell us if a visual was
supported.  An older message on this list (subject "wxGLCanvas: empty
(default) constructor") talks of why the default constructor was
removed, but mentions that it might be acceptable to put it back in
with the new, separate wxGLContext creation.  Any thoughts?
