The paintComponnet method of the JSVGCanvas just draw a BufferedImage that
represents your SVG drawing. The size of the image is set according to the
size of the component. That means that each time, the paintComponent is
called, the whole surface is covered by the image.
You could draw your stuffs *after* calling super.paintComponent. In that
case, your drawing will be done on top of the image.
Hope that helps.
Thierry.
