Annoyingly, I've just figured out a quick fix for this...
For boring reasons, I can't get git working on my machine at the moment,
but just add:

m_LockedMatrix.remove_scale();

after doing the blend in Camera::DoCamera().

It's probably still a bit wrong, I think a slerp would still be better.

How did the gig go anyway?
