Layout Information for SVG Elements

Looking at Issue 1953 for Firebug, I can see that Firebug does not do
anything useful for SVG elements in the layout panel. The layout panel
displays basic information about an element (height/width, padding,
margin, offset). I'd like to get at least some basic information for
SVG, and perhaps setup the panel to be extensible for a Firebug-SVG-
extension. I already have the Edit button for a SVG element have a
hook for a extension developer to swap their editor.

But back to the issue at hand:

What basic information could be there, and how to get it?
