R. Timothy Edwards e04307c085 Corrected an issue in computing the extended (includes area of 
label text) vs. non-extended bounding box of a cell when doing
"getcell" (and probably a number of other commands/functions, as
well).  A function was always computing the extended bounding box
and then setting both the normal and extended bounding boxes of
the cell to this value, resulting in incorrect cell selections.
