Colin,
I re-based the patch that adds camroll and camzoom to the current tip, added
the unwind_protect blocks to the tests and moved __rotate_around_axis__.m from
the private folder so that functions in the "draw" and "appearance" folder can
access it.
Wrt to the "camzoom" function, I changed it to interpret the zoom factor
differently: A zoom factor of 2 makes the objects in the axes appear twice as
large. That also fits quite well with the results from Matlab.

Sorry for the long delay. I'll try to review the other patches in this report
soon.
