0.9.20 - camera scaling issue?

I broke something while working on the new head mounted camera system - it now needs to be able to work without doing lens calibration, so I added a flag to tell me if the lens was calibrated or not, but wasn’t properly setting the flag if you were loading an existing calibration instead of just doing a new one.

Those of you having trouble, please try this version and let me know if it’s fixed for you:

If that works, I’ll roll it out.
