My only concern about that approach -- if I understand it correctly -- is
that this path clipping would have to be redone at every change in view
limits. Wouldn't that mean that in order to support panning and zooming, we
would need to keep an original copy of the SVG data and then create a
clipped version of the SVG data to post into the QT widget?
