I think I understand the problem. Unlike say a 'rect'
element the 'use' element establishes a new user coordinate
system based on it's x,y,width/height attributes. Since
getBBox is always returned in the local user coordinate
system it may appear that you are getting the bounds of
the symbol element.
What you appear to want is the bounds of the use element
in it's parent's coordinate system. In which case you
will want/need to get the transform from the use to it's parent
and apply that transform to the bounds returned by
'getBBox' (which is really preferred over getting the bounds
from the graphics node).
