Art of Illusion

Thanks, I'll take a look at the other spots. Remember that this change is only applicable to subclasses of ObjectViewer, since that's where the ability to switch between local and scene coordinates is implemented. So some of those instances are fine as they are.

The rendering of the rest of the scene in ObjectViewer didn't work correctly either, but it required a slightly more complicated fix. I had to add a sequence of two transformations to get the correct coordinate system for each object.
