Initially I hooked it up so that it happens automagically, but I was told by our GL expert that I could just update the objects when they're (re)bound. This approach is based on the rules listed in appendix C of GLES 2.0.25 spec. I haven't actually tried that change yet. -- Ville Syrjälä _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
