I notice that, even in the SVN trunk, osg::State::setVertexPointer
doesn't check if the new vertex pointer is the same as the one that's
already set (the check is commented out). My application is getting some
significant overhead because glVertexPointer is called by every

sure what the best way would be. I intended my email more as a call out

Update callbacks replace the standard traversal (see osg::NodeCallback's
header file), so you have to call osg::NodeCallback::traverse() to
traverse the Node's children. So:
