We don't expose it through any of the Swing change API's.

See above...

The one thing you need to consider is that the rendering transform
does interact with the viewing transform (From the viewbox). So in
the case that the window that is viewing the document is a different
size/aspect ratio then you may need a different rendering transform
to get the same 'view'.
