"Transform entire scene" in virtual reality sets Magnification to Inf

[lucsdjango]

(Possible duplicate of #102)

When attempting to transform the scene by pressing the grip buttons on both virtual reality controllers (following instructions in README.md), Magnification is set to "Inf." (division by zero?) and everything in the scene disappears from view.

Matching the reference view, resets Magnification but as far as I can tell there is no way to use the grip buttons in virtual reality.

Tested in 5.2.2 and 5.3.0, with Vive and Oculus touch controllers.
