However, when the scaling factor is set to 1.5, for example, the output is messed up. The VGroup is no longer centered. It's actually gone off the screen. I think what happened is that the outer Group was blown up by 1.5 (of which we can only see a portion) and the VGroup is centered in that blown-up space. How can I get the VGroup to be 1.5 times larger and centered on the screen?
