After recent changes, navigation in the brain viewer is broken

It happens in the Brain Visualizer.
Clicking on the X, Y or Z sections in the right, should let you move the navigator and face objects (thus reposition the point where the sections are made).
Currently these work only when the brain hasn't been moved from the original position (e.g. as reset by SPACE).
If the brain had been rotate or moved in any way, clicking on the sections in the right moves the navigator in what appears to the end user as bogous.

The simplest solution would be to simply move the scene in the main canvas in the "SPACE position" when the navigation on the right is happening, but a solution where the sections on the right are still functioning even when the actual scene is rotated, would be very much preferred.
