Lazy state updating done in osg::State is done using pointer

Of course you can do that - it just wastes quite some memory for
indices, considering that automaticall

Hi Frederic,
I have a quick look up on the GL primitive restart and understand it a
bit better now. As this feature has to be enabled/disabled using
glEnable/glDisable it naturally would be an StateSet::setMode() rather
than something embedded in a DrawElements. The

Hey.
Now comes a non-trivial one... :-)
A while ago I added support for primitive restart to our internal
build to stitch triangle strips - this greatly improved performance
and VRAM usage for our very heavy CAD data. As primitive restart was
included in GL core a while a ago I suppose this featu
