(look-recenter [objectID] [cameraID])
- Translates and rotates the camera so that it is looking in the
-z direction (in objectID's coordinate system) at the center of
objectID's bounding box (or the origin of the coordinate system
in non-Eudlidean space). In Euclidean space, the camera is also
moved as close as possible to the object while allowing the
entire object to be visible. Also makes sure that the y-axes of
objectID and cameraID are parallel.
