The JSVGCanvas actually renders to a BufferedImage the size of
the component (in your case getPreferredSize()). You will need to
implement/handle some of the scroll notifications (or you can trigger
a repaint with the new scroll parameters on paint with a translation -
so some background will show for a little bit before the new rendering
fills the area).
Doing this well given the potentially expensive cost of rendering
the SVG content is tricky...
