Well the simplest thing is to set 'overflow="visible"' on
the root SVG element.

I've tested this before and it has worked. Are you sure your
'xxxx' is a valid viewBox specification? I should also say that
setting the viewBox is a very expensive operation as we have to
rebuild the entire graphics tree because any attributes that use
percentages are likely to have changed.
