Since commit e8662bea31, we're using OSG functionality that contains an unfixed crash bug in version 3.2. The bug is fixed in version 3.4 (OSG commit 6351e5020371b0b72b300088a5c6772f58379b84)
This fixes initWorldSpaceParticles not taking object scale into account. Still not taking into account object rotation or node animations. Ideally the initWorldSpaceParticles needs to run in an updateCallback.
OSG 3.4 adds the ability to place Drawables directly in the scene graph, without a Geode decorating them. Leveraging this should give a small performance boost, because the redundant Geodes increase culling overhead.
There is still an oustanding issue with the RemoveDrawableVisitor no longer working correctly, because Drawables can have multiple parents.
For now, not much difference, but should result in a sizable speed up once MyGUI no longer needs the DYNAMIC flag (i.e. the loading screen truly renders in the background).

Checking for emptiness using size() might be inefficient, because
it can take linear time, while empty() is guaranteed to take only
constant time.
For non-primitive types, postfix ++ operators are inefficient
compared to prefix ++ operators, because post-increment usually
involves keeping a copy of the previous value around.
