Bug#211765: Final SGI licensing update

[Brett Smith <brett@fsf.org>]

Hello again everyone,

I just got word from the X.Org team that all the developers who worked
on the files that were under the GLX Public License have given their
permission for their contributions to be used under the new permissive
terms.  I believe that all the code in X.Org that was originally under
an SGI license is now free software.  Once the latest stuff gets
incorporated into Debian, I think this bug can be closed.

If anyone has any questions about this, please feel free to ask me.

Best regards,
