I personally like this approach better. Then we can leave the current
rate of progress bar update in MoveTab as it is (per column per sheet).
Still, I would like to get my 2nd suggestion (of having the method
receive a pointer to the existing progress bar instance instead of
creating and deleting it per call) implemented, to make unit-testing of
this method possible (by having the unit test code pass a NULL pointer
to this method to ignore progress bar updates).
