testcase

When you change the url of an SVG image a wrong area will be invalidated:

When you open the attached testcase you see an red rect on position 100,100 with the size 50,50. This is an image. When you click on it, it will change the url of the image. Now the area at 100,100 with the size 50,50 changed. You get the correct invalidate rect at ChromeClient::invalidateContentsAndWindow, but addional the rect(0,0,50,50). This requests an unneeded area for repaint.

The wrong rect is generated at http://trac.webkit.org/browser/trunk/WebCore/rendering/RenderImage.cpp?rev=64272#L179.
Is it correct that this code is called for SVG?
