I'm not clear which commit you are referring to - there have been lots of
commits to State.cpp so a bit tedious to check through.

I've moved the State::initializeExtensionProcs() function in 3.4 to the
same position in the State.cpp as the master version to make it easier to
see diff's between them, and have changed the State::_glExtensions setting
to be consistent with the one in master, hopefully this will be sufficient.

Could you let me know if these two commits to OpenSceneGraph-3.4 work fine?

Robet.
