Hmm, I'm not super familiar with the Qt layer in VTK. Perhaps someone else
on the list might know?

Looking at the QVTKWidget implementation, I don't see why the Qt version
would make a difference regarding MSAA. Let's see if someone on the list
has any ideas, and I'll ask around to see what I can find out.
