Pointer Events in SVG

Hi,

just to quickly introduce myself, I work at Vodafone and contributed to the
WICD Testsuite.

I would like to know, is there a way to get the pointer-position in
reference to an SVGs coordinate-system? Please take a look at the following
testfile (with Opera 9.23, Firefox2, Safari3):

The blue rect is part of an SVG that has a viewBox of only 20 x 6, but the
whole thing is in a container much bigger and is therefore scaled up. When
hovering the SVG you see some properties of mouse-events below it, but none
of them quite fit
the SVGs coordinate system. The maximum x-values for that would be 20 then.
I think it would be important to have an easy way for getting to these values,
just thinking of a simple mousefollow, or slider controls, for example.

Thanks a lot,
Daniel
