This can vary a little depending on the SVG implementation but
in general getScreenCTM will give you the transform to the screen which
is generally a pixel based coordinate system (it can vary for example in
print contexts). I believe that one unit in the screen coordinate system
will correspond to one pixel on the display. Based on that you should be
able to calculate a scaling transform to map the bbox of an element to a
particular size in the screen coordinate system.
