It is true that an SVG implementation must fit the viewBox to the
available Width/Height.

As I think I mentioned earlier you can modify
JSVGComponent.calculateViewingTransform (perhaps to always return
the identity transform). I'm guessing that they don't limit width/height
in any way so the viewBox is generally mapped 1:1 to screen. Batik
limits width/height to screen size.

The code below looks mostly right to me (see comment below).
So without any more information on how things are failing (how
far are they off, how you are determining what is right vs
wrong, etc) I can't help.

This should probably be canvas.
