Unfortunately we're still missing a good testcase, if the bounds of an object change from "bigger" to "smaller", eg. changing the stroke-width of an rect from 20 to 1. So this regression was not noticed. I have a fix with a testcase that's broken on trunk and fixed with my patch. As side effect the caching of the repaint/object/stroke bounds is simplified - we even save a FloatRect per RenderPath. Overall this is another huge performance benefit :-)
