[osg-users] FrameStamp in osg::State

[Riccardo Corsi]

@Jannik ahah sorry, I didn't realize from the author's name :D  I
remembered the post as I've successfully used a solution similar to yours
to render DYNAMIC elements that I want to render at the end of the frame.

Anyway, as the frame number issue is fixed, no more need for workarounds.
Cheers,
Ricky
