vsgturntable models/teapot.vsgt
~~~

The up down movement with the left mouse button rotates the view around the models X axis in a natural way, but when I move left and right the scene rolls around the models Y axis.  The later feels really odd.  I was expecting the scene to rotate around the models Z axis, like it was placed on the record turntable.

Is the behavior how you meant it?

There is also the following compile warnings, I can easily fix this myself but mention them in case they are hint of something that was intended to be implemented but not yet completed.
