Repro case

Steps to reproduce: 
1. Open attached mininmal repro (svg_getIntersectionList_CTM.html). 

This repro sets up a simple scene (rectangle at origin) and calls getIntersectionList multiple times, resulting in an empty NodeList (expected behavoir is to return the rectangle element).
Calling getScreenCTM() (note: this can be called on either the root SVGSVGElement or the SVGRect) and calling getIntersectionList now returns the correct result.

Correct behaviour under IE9 and Opera.
