I will probably push a similar branch this week that removes other extensions discussed at XDS. See "kill it with fire" at the bottom of http://www.x.org/wiki/Events/XDS2010/Program. It looks like the biggest savings will come from removing GL_EXT_paletted_texture and GL_EXT_shared_texture_palette. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkyXbCwACgkQX1gOwKyEAw9S4wCbB2qpT9MVWO+Ifl+7mb6lnxr0 Ba4An1pFUeEE4hcsWNc5f/BmiCJNRRFS =xRnA -----END PGP SIGNATURE----- _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
