Intrinsic calibration switch between models
When loading an old project, value for new model is set and the undistortion is not correct anymore (here: k4 = 5):
When move to old model after the new model has been used before also values of new model stay and have an influence:
The values of the new model could stay so that one could switch between old and new, but when the old model is enabled the new values should not be used for undistortion.
