Description Alexandru Chiculita 2011-11-24 06:24:41 PST 
Filters are not applied correctly when the layer has a transform. The current behavior is that it applies the transform inside the "filter area" resulting in clipped graphics. Moreover, the rootLayer is always passed as being the filtered layer, which is wrong. When there's no transform applied, the rootLayer should be just propagated. Otherwise the clipped rects are calculated incorrectly and an assert fires.
