You can set the width/height on the SVGGraphics2D with:
SVGGraphics2D.setSVGCanvasSize(Dimension d);

There was a problem in this area in the 1.6 release I think it's
fixed in SVN.

Yes, rendering complex SVG's can take a long time. Since we
can't control this we use the last finished rendering until the
user decides on the new view.

Probably, I don't really have a problem with adding get functions for
the SB instances, it just hasn't been needed to date.

This is very hard to do. Since the rendering is async you need
a fair amount of tracking logic so that the paintTransform and the
renderingTransform don't step on each other.
