do essentially the same thing.  If a 'glGetString(GL_VERSION)' call
returns a string with a version greater than is supported in protocol,
wrap that version string with as with 'sprintf(s, "%s (%s)",
supported_version, returned_version);'.  Currently the top version
supported is 1.2.

The jury is still out as to whether or not this is the right thing to
do.  The other option is to just replace the returned version string
with the highest supported version string. This would lose any extra
informantion in the version string, but may be safer.
