OK, but I don't think BoundBox will work. You want to have it correct based
on the current zoom. Send me some files and I will do some testing as well.
Needs checking:
1) shift the center to various points within the window using CTRL-ALT
2) zoom in and out
3) rotate model that is long and skinny, such as 1JEK, 90 degrees and ensure
that is working properly as well
