Again, I never get the normalized values in osgWidget (and haven't since
I began writing it). This has to have something to do with the kind of
camera the event appears within, as looking through the code I see that
the event{X,Y} values are calculated two different ways depending on
whether a function getFocusedCamera() returns true or not...
How is your scene laid out? I've never used CEGUI with OSG, so I'm not
sure how people in the past have done it.
