Hi,
I'm running OSG in single threaded mode and making the calls right after the
context setup code, but if you think that the scaling operation needs to be
done within the OSG's inner threads; then there's no chance that I could use
this function. If you suggest an alternative, I'll follow.
Regards,
Can
